I have an 04 Alero and was wanting to know if the heads will fit on a 99 Grand Am. And where do I find a vehicle parts interchange information at?
Hey there, New to the site and have a question before I screw up and get a "told ya" remark. I have an 04 Alero with the 3400 motor and a 99 Grand Prix with the 3400 motor. The 99 Grand Prix has a cracked head I'm sure since it was run hot after a wreck and has the telltail sign of milky colored oil on the dipstick. Question is will the 3400 from the Alero fit without any mod into the 99 Pont or will it be a bad idea?

how do you reset the schedule to 100% on a 2003 Buick lesabre.
I have found 2 methods and would like to know how to do this reset after an oil change.
here is what I found on it>
some say stomp the gas pedal 3 times fast with Ignition on ,
others say use the Eng/MET button I never touched this maybe you can help me .
Buick LeSabre, Park Avenue, 2000-05
Turn the ignition to ON. Press the GAGE INFO button on the driver information center (DIG) switch to view OIL LIFE INDEX. Press and hold the RESET button on the DIG until the display reads OIL LIFE INDEX 100% NORMAL. The engine oil life monitor is now reset.. Turn the ignition OFF.

Need some help I have a 1997 Chevy S-10 that was running, I bought it and drove about 10 miles and ran out of gas. I put new gas in it and the truck would start but would not take gas. It would just idle and when put in drive it would pull itself but still would not take gas if you pushed down the pedal it would die out it has a 2.2 liter engine if that makes any difference.
If battery is charged car will start and run the voltage at that time is around 12 volts at battery.
- Voltage starts dropping until Voltage reaches around 6 volts and car dies.
- If I leave jumper cables on it will keep running.
Things I have replaced:
- Ground cable from battery to starter and chase ground
- Had starter checked it check out OK
- Replaced the ignition switch
This started with the car would not always start you had to giggle the key or something then most of the time it would go ahead and start then it got to the point it would not start.
Still acts like a grounding issue but with a charge on the battery if I check from the engine to the battery I get voltage OK.
- From different places on the engine including the alternator I get voltage.
The shifter on my 2002 Rendezvous slides but does not shift any gears. It is stuck in park.
First... Is there a button or something that I can do as a quick fix? I need to be able to move it out of the street.
Second... What is the issue and solution?
Thank you in advance.
I replaced my thermostat several months ago due to it over heating. Then, about a month ago, i topped off my radiator fluid, and forgot to put on the cap, resulting in all my fluid escaping and over heating my car. i added fluids and the worked fine, no over heating issues. Howeer, it the temp guage would never go above cool. So, i replaced the tstat again, thinking this was the issue. Now my car seems to want to over heat. goes all the war to 3/4 hot. What do i do now?
I have a 2003 buick lesabre custom, I changed the valve cover gaskets, and now I don't have heat. It started to warm up as I drove, then just got cold. Still blows, but only cool air.
Vehicle is a 1990 Buick LeSabre. Ran great for a while. Occasional minor drop in idle but nothing concerning. Recently engine would stutter when giving gas at 45 mph+. Maybe twice during a 20 mile trip. Been like that for months. Here in the last month it idles rough more often. Acts like its going to die when accelerating from stop. Does die when using reverse 75% of the time.
Added fuel treatment, no help. Plugs and wires replaced less than 7 months ago.
Unplugged Mass air flow sensor and ran it down the street. Still acting as before.
Here's the codes I got from auto store.
GM 21 thru 26
GM 32 thru 35
Im going to attempt cleaning the resistors on the Mass Air Sensor by dripping some rubbing alcohol on them.
Any help much appreciated!
2003 Ultra where is the temperature sensor located on 3800 engine, cooling fans do not come on until A/C is started.
We recently bought a 1999 Buick Park ave, the car runs great starts just fine until the temp drops below freezing. then it will not start until the weather warms above freezing. The car cranks over just fine, not a battery issue. just will not fire, dose not even act like its trying to fire.
2002 buick rendezvous cxl - just had starter done last week and yesterday had alternator done. Changed a high beam bulb last night and right after when I started the vehicle & turned the heat on, the climate control display went black and the fan quit blowing. Checked inside fuses 30, 26, 39, and 41, they are good. Not sure if related, but today the wipers quit during mid wipe. It's a snow storm here and can't drive my vehicle without the heater working and now without wipers. Any ideas are greatly appreciated!
Where is the oil level sensor located and how do you replace it? Does anyone have an image of the location?
My Saturn just started knocking after I got on the gas a bit it's good on oil was wondering maybe a spun a bearing or any other suggestions still runs but is on limp mode.
I have a 94 buick park avenue that has an idle problem. I recently had the harmonic balancer replaced and ever since it likes to idle high and hold high rpms during driving or sometimes when it gets down to normal rpms either by itself while idling or when i come to a stop it starts to struggle and a couple times it has died. I have looked at all the vaccum lines and they are all attached so i checked the accelerator arm and that seems fine. Looked at the intake manifold and everything seems fine there. I do know i have an exhaust leak from where the donut gasket goes but that was like that before the balancer replacement and it didnt have this problem. Any ideas, maybe harmonic balancer on too far or not enough? Also it doesnt want to communicate with a scanner. Also i dont have a service engine soon light on anymore.
How do you replace the interior door lock sliders in a 95 Buick regal?
Have a coolant leak, but it is not external. A very slow leak
I'm getting these symptoms second hand for a 2002 Le sabre Limited. It will do 45-50mph on hiwy without touching accelerator. I've been told accelerator is not showing any depression when driving and butterfly no open in park. Then put in neutral rpm's come down then put back in drive and it repeats. This wasn't as bad to start then got progressively worse and now constant. When in park idle ranges up and down 1200-2000 rpm's. All these symptoms occur with the cruise and A/C on or off.
Check engine light has never lit up. No codes. All sensors have been monitored with normal readings.
Throttle body has been off and cleaned. MAF, IAC, TPS, MAP, PVC all changed. Plunnem was checked for cracks when T-body off. Ether sprayed all over engine with no change in idle and no vacuum leaks can be found.
Cranks and starts normal. Does not miss or hesitate. Any Ideas?
I have a 2003 buick regal,and when I try to start it the instrument lights flash,and it makes a ticking noise when this happens. I have replaced the PCM and the instrument cluster. also checked the battery connections. the starter will kick out but kicks right back in. please advise.

Hi car experts, I'm hoping you can help me fix my car. Below is a description of my problem, and things I have already tried--thanks, Beth.
My well maintained 1998 Buick Century, with 160k miles, is idling funny, but only when warmed up. If I start the car when it is cold, starts fine, runs great. If I start the car when it is already warmed up, like after filling up with gas, then it might not start on the first try. And once it does start easily, or may start and die, and once I get it started the idle goes way up and down. I've tried to fix it myself as I don't have a lot of money, and would like the car to keep running for a few more years. After reading, and trying lots, I came to the conclusion, since it runs so well at other times, that it might not be a serious problem, but a sensor that is giving the car bad info. I read to unplug sensors one at a time to figure out which one might be bad. When I unplug the MAF sensor, the problem goes away--I felt pretty proud that I had figured out what ails the car. I bought a new MAF, installed it, but the problem is still there. Aside from the MAF being bad out of the box, what might be my real issue? Could another sensor or problem be hidden when I unplug the MAF?
What I've tried:
Car has good compression. I tried what I saw on youtube, and sprayed carb cleaner on all the hoses while it was running, to check for vacuum leaks, this did not change the idle speed, and visually, despite their age, they all look good. I have put in new spark plugs and wires. The check engine light is on, but the folks at Autozone say it is only the evap system--I tried a new fuel cap, that didn't make it go away. Could the evap system cause idle problems such as this? And if so, why does unplugging the MAF make the problem go away?
The only problem that exists with the MAF unpluged, is when I first put it in gear to drive, the car loses power when I go to step on the gas, but only the first one or two times, after that car runs totally fine--is this what the car should act like with the MAF unplugged? But if I plug in the MAF, the car doesn't lose power when I first step on the gas, but once heated up and I restart it, it does the crazy idle.
Any help or thoughts are appreciated,

I own a 2004 LeSabre that doesn't have heated external mirrors. Besides the mirrors themselves, what else would I need to replace to have heated external mirrors? The car has just under 70K miles, so a little expense would be acceptable. Kevin
you should have it scanned for codes and pending codes. drive it with the scanner reading the data stream and see if the torque converter is have a problem with the lock up. or if the trans is going in and out of overdrive, Or if the computer is reacting to a sensor problem.

I took a supercharger lower intake manifold heads fuel pump and wire harness with computer and fuse box from a 97 gtp and put them on my 99 grand prix gt I'm having wire issues running lights stay on when key is not in also idling very rough could be a bad fuel injector but can't get readings from computer I'm going to get a harness from a 99 gtp and see if that helps . Wondering if anyone has done this and what problems they had or tips they can give
I got a 99 regal runs perfectly fine only issues is the car overheats because the fans will not turn on. I unplugged the temp sensor plug and the fans automatically kick on so I know its not relays or the fans. What could it be?

I have a 2000 Buick LeSabre and the computer is saying it is the vacuum modulator, where is it located?
After fixing the idlen and stalling issue, my 94 lesabre battery light keeps coming on and eventully shuts down, ive replaced the battery and alternator 3 times, my question is what can continously kill an alternator??? Please help
I have a 93 Buick century special 3.3 v6. It has new catalytic convertor,new throttle positioning sensor, new oxygen sensor, new pcv valve. It runs great the gears on dash are 1,2,D no circle around it just causal D when i try to accelerate best way to describe it is feels like its choking itself out. I have to feather the gas to get it going. Before i know it im 35mph before it shifts from 1rst to 2nd after it hits drive its fine if i have to slow down enough to down shift to 1rst it does it all over again i cleaned maf too i asked couple mechanic about my car one said sounds like a bad ecm i checked auto parts store for price they said my cars transmission doesn't run off the ecm a 4 speed does a 3 speed doesn't. The other mechanic said could be shift solenoid or pressure modulator both $30 parts how long does is take to replace a shift solenoid? Or pressure modulator? So i can figure what I'll pay labor for my mechanic to change them he
1994 Buick Lesabre Keeps idoling High and stalls when coming to a stop or making a complete stop. The service engine light stays on most of the time then goes off but comes right back on. The battery light plays peek-aboo with me I replaced the Battery and alternator and the light still comes and goes. It idols high and then goes back to regular then idols high again.. I replaced the throttle sensor, its still doing the same thing. Car never cuts off untill you are slowing down to make a stop or you stop completely and then slowly cuts off like you are out of gas. I have taken the car to two different shops so I could get the code reader put on and both places are unable to read anything its like it wont connect???? I dont know what else to do It sounds like possibly there is a vacuum leak somewhere when the engine is rev'd but nobody can find one anywhere I dont know what else to do someone help!?!?!
Air will not blow through my vents on my 95 park ave, I have replaced the blower motor and still no air. What could be my problem?
This is pertaining to an electrical/ignition problem for a 95 Buick LeSabre with 94k miles. The car battery is consistently dieing. I have 7 amps drawing from the battery when the car is turned off. The battery is brand new, I have replaced a replacement just to be sure I could eliminate the battery however it is the $80 battery from auto zone so theres a slight chance it could be the quality of the battery. I have taken it to my buddy to test parts on the car that draw power when the car is off to see what might be sucking the juice from the battery. The car will not be able to start 3 days after it was last turned off. The odd thing is the car started the past three straight days, I can it to recharge the battery and when I went out today to start it, the battery was dead. This is the first time any thing like this has happened to the car.
Do you have any suggestions on why this is happening? I’d be glad to answer any questions that would provide additional insight into my dilemma.
Yes, each gauge has a stepper motor that control it inside the instrument cluster.
I found a picture that may have the parts you described
Yes, you could have a plugged catalytic converter. They can also set EGR codes. The proper test is to use a back pressure gauge in the oxygen sensor port. But, you can unbolt the exhaust at the rear manifold from under the car, ahead of the converter then see if power and acceleration is restored.
You could also have a faulty MAF sensor. You would need to look at airflow readings of MAF to see if they increase as RPM increases. You can also unplug it when it is running, if it dies- restart it, then see if power is back to normal.
I would also check the fuel pressure regulator. If it was leaking, that would cause the very bad gas mileage, and could be the cause of a plugged catalytic converter.
If it is wearing that badly, either the strut has been pushed way out of alignment, or more likely since you have movement you describe, the wheel bearing is loose.
Have that wheel off the ground, move it to get it to wiggle and have someone look at the ball joint and strut. If they are not moving, but the axle is, then the hub bearing is bad.

stays there untill i reach the top and motor rpm come back
to 1800 again 65 mph, now on a up pull or on a level road
going over 50 mph in overdrive rpm drop to 1200 steping on
gas pedal rpm still 1200 step harder still 1200 if i tap the
gas pedal up and down fast rpm jumps to 1800 and back
down to 1200 again a few seconds later this go on and on
until i slow down to under 50 mph and in 3 gear rpm stay
at 1800 and every thing works ok no more tapping the gas
pedal just takes more gas to get somewhere.
when the rpm drop to 1200 going up hill car stammers
because motor running too slow to pull the load
question is what makes the motor speed up to 2500 0r
3000 and stay there in [ overdrive only] over 50 mph gong
up hill thank you hope this helps you make a better
analycis note this in overdrive only 4 gear that i have
ok, be careful. keep in the back of your mind that the spring holds the weight of your car up

Any thoughts or ideas would be appreciated. Thanks in advance.
Plenum replalced almost two years ago by neighbor. Took it on long drive afterwards and it had a very small misfire when driving it I could feel it. I let the car sit for almost two years and just recently had my mechanic look at it. He had to replace brake lines and fuel lines and fuel filter. He is not the person who did the plenum repair. btw, because of previous history with an olds I knew about the white smoke and dexcool and shut car off the first time I saw it and there did not appear to be much damage other than the plenum so the neighbor said.
My mechanic said the engine sounded fine and he took it for a ride. I picked it up two weeks ago and am having terrible gas mileage and smelling pure gasoline when I start the car and back into it. Engine lgt. is on. Sometimes blinking. Drives good. slight misfire when in D,R but not in P OR N. My mechanic is on vacation. I am a female. Ok, lol, what could be the problem. Thanks guys, so much.
you would have to see if you have spark and injector pulse. Without a lab scope or scanner the way you can tell if you have a cam and crank signal is to check to see if you have spark to the spark plugs or the injector pulse to the fuel injector.
