intake air temp control sensor

Where is this part located on a 2010 silverado 1500 v6?


92 Silverado K3500 7.4 L

Ok... Uneven and sometimes surging at Idle. Smells very rich at start up. It will run at low RPM, but when Accelerator is pressed, falls on its face. Now after about ten minutes of nursing it up the hill to work... it will begin to run normally. I have changed Mass Air flow sensor, O2 Sensor, Therm Temp sensor, Another sensor that runs the cooler fan, and Finally The Throttle position Sensor. Only ting left is the EGR valve and many have told me to just clean it out with Carb cleaner and re install., which I have done. I did learn that Throttle Position sensor should be Calibrated ...LOL How the Hell does one accomplish that?

Any Help? You guys have always been great.

Throttle position sensor

What is the best replacement throttle position sensor for my 2003 silverado 5.3l


Keyless remote entry

Remote entry not working. New remote won’t program. Replaced receiver unit under under dash but the two used ones would not program either. GM in all their wisdom has discontinued the receiver unit and has no replacement. Junk yard part only. Anyone else had to his problem?

91 Silverado Just died as I drove. Now won't start

I was driving and truck just died. Tried to start back up. wouldn't. Changed fuel filter, added fuel cleaner in case fuel filter was clogged. still no start. It turns over but won't start. Battery is good also. What else could be wrong with it?


02 silverado 1500 4.8

I cant figure my fuel pressure problem cant get it above 52 psi changed the pump.filter,regulator when key is turned on it jumps to 60 then immediately drops to 50 running its at 48-50 it jumps to 60 when I take the vacuum hose off regulator any suggestions


Vortec 7.4l fuel pressure

I have a 98 k2500 with a 454, 130,000 miles on it, and am having issues with random misfiring under a load. I have replaced the cap, rotor, plugs and wires, and the issue has come back after only a few hundred miles. I checked my fuel pressure, and it has a solid 60 psi at idle and with the key on/engine off, but when given some throttle, it drops to around 50 or lower, and doesn't seem to gain any psi as the throttle is held down. Is this an indication of a bad fuel pump or plugged fuel filter? I have both parts brand new, waiting to be installed if so, but don't want to put them on if I don't need to. Please help!


2004 CHEVY SILVERADO GAUGE SEAT HEATER ISSUES

So all my gauges are wacked out on my truck, they work intermittently and then the needles will just drop. all or different ones at different times and then some will work again and some wont. Just depends on the day, also when I'm rolling down my driver window, my seat heater turns on. Is this all interconnected? maybe a computer problem? Driving me nuts!!!


1992.Silverado K3500 7.4 Liter,Manual Trans

Pulsing Idle... Sometimes accompanied by "Service engine soon" light. it s about 100 RPM pulse. Then it will smooth out and then it will start again. O2 Sensor or some other Sensor , or Fuel Filter...Its been a good long while since I ve changed that. Runs fine other than the Idle Bug..

Power steering issues with hydroboost

My 98 k2500 with vortec 7.4l has hydroboost brakes, and at idle and just above idle rpm, it has no power assist in the steering. Even in neutral while revving the motor. Once moving and rpm increases, the power assist returns. Is this a sign of a bad pump, or weak pump, and are the power steering pumps the same for hydroboost and non- hydroboost equipped vehicles? Would fluid contamination be a possible cause of this?


Alignment

I have a 98 K 2500 with 8600+ GVWR and 454 Vortec motor, I'm in desperate need of front end alignment specs as I cannot find them anywhere on the internet. I have searched multiple combinations and looked for three days and I can no longer search the internet without losing my marbles! please help! thank you

2003 Silverado Leaking

My 2003 Silverado is leaking an oily brown liquid from the front, through the grill. Can you please identify the part? Thanks


2005 2500hd burnt wiring on neutral switch

Purchased a used camper and was pulling it home from town 2hrs from where I live. Lost lights on the way home, pulled over to check fuses blown my ign fuse in the fuse box under the hood. Check wires in steering column, nothing. Tried to jump starter didn't have enough juice. Stuck in bfe for 3 hrs so called a cab went to wally world because it was midnigh. Bought a battery installed it and it fired right up. Now I was short on fuses so I left a 20 amp in my 15 amp ign that kept blowing. Next day leaving a store go to crank it up nothing. .... tapped on starter fired right up. ... got home nothing ever since tested starter fine...power to the ign fuse, further investigation found a burnt plug on my transmission neutral safety switch. Ordered one from a local parts store for 180 bucks. .. get it and it's only a7 wire. ...mine a12 place would exchange since it was a dealer order bs.... so I decided to make the older clip work done the 7 wire plug didn't have the lil clips on the inside to add more wires to it. Starting pulling wire and noticed my red wire was melted and had melt wired a good 12 inches before the plug. Took plug apart and rewired the pins I could and use the one out of the new one as well. Metered all the wires make sure I put the right wires in the right pin slots. While installing the clips I noticed there were more melted wires further back so I checked and rewired any wires that looked problematic. Buttoned it all back up worked great for 1/2 day then same thing now Ive pulled the relay (which is good) and use a wire to basically bypass the switch. Is there a way to test the neutral safety switch in this situation? Now I turn the key on pop the hood jump the switch truck starts great however the gear indicator doesn't show when it's in park and will appear once truck is in motion. Are the odds are there are more burnt wiring that's causing this or could it be the switch? Any help would be greatly appreciated


Replace hydroboost with vacuum assist brakes

I have a 98 k 2500 with hydroboost and have trouble with the system, and have heard they are prone to brake calipers sticking on and catching fire, etc... plus mine is leaking hydraulic fluid so was wondering....what does it take to convert hydroboost to vacuum assist power brakes


2wd transmission in 4wd

Can a 2wd 4L80E be adapted to work in place of a 4L60E in a 4wd truck/SUV like the 2wd th350 can be used in place of a 700R4 in a 4wd? I have done the 350/700r4 swap before but I have little knowledge of the newer transmission specs as far as output shaft length etc. I do know that the 80E has a bigger output shaft diameter than the 60E but I also have a t-case that came factory behind a 4L80E. Just don't have the 4wd transmission to compare. Any insight is appreciated and thanks in advance.


Re: Starts bit doesn't stay running

Ok, I haven't gotten a new starter on it yet, so I haven't checked for injector pulse, but for argument's sake, let's pretend there was no injector pulse due to the passlock system shutting it down...what would be the remedy


Replacement engine

Will a 5.3 from a '99 Silverado be a direct replacement for a 5.3 in a '01 silverado without changing any sensors, connectors, or accessories, etc.?


NEED HELP! 2005 Silverado Idle Problems

This is nothing new to my 2005 4.8L Silverado. Usually the problem came and went but now it's staying. As soon as I crank my truck the electric fan cuts on and idles rough. As soon as I start to drive and apply throttle the temperature gauge goes from min to max (typically stays at 210) and the engine almost dies and cuts off, almost like it has bad gas. When I idle in drive the truck revs up and begins to speed up. Have big plans for the truck so I need help as to what to check or replace! Thank you!
