1995 aurora sputters and then stalls out.
I have a 1995 oldsmobile aurora with a full tank of gas it will crank up but when I press the gas peddle it sputters and then cuts off what could cause this to happen?
Re: 1995 aurora sputters and then stalls out.
you should check your fuel pressure. spec is 41 to 47 psi key on engine off

04 Oldsmobile Alero has No brakes!!!
Have an 04 alero that just replaced the brake, cut the rotors, replace the passenger piston due to it was stuck,and bled the brakes.a month later i was driving and now i couldnt stop. The pedal went all to the floor and there was no fluid in the resevoir.i see no leakage anywhere. I put more fluid but the pedal still goea to the floor...can someone help???
Re: 04 Oldsmobile Alero has No brakes!!!
if the master cylinder's reservoir was empty, you can be pretty sure it leaked out somewhere. you just have to find out where. Once the master runs out of fluid, when you pump the brake pedal you are pumping air into the system. Filling the master after it's gone empty will still have air in the system. It will have to be bled out. That may be a problem because when you try to bleed the brake system you will also be pumping fluid out where ever the fluid leak is.
you need to find out where the brake fluid went. If you can't find it, you may need to have a shop or some professional find it for you. Once you figure out where the fluid went, you can see about servicing the system to bring it back up to snuff.
if you cannot find any brake fluid anywhere on the vehicle where it leaked out you might want to unbolt your master cylinder and see if the booster has fluid in it from the back of the master.

obd scan shows codes p0113,p0443 and p0449. where is the iat fuse for a 2002 olds alero located so can check to see if its blown ?
Re: 2002 olds alero obd codes
P0113 is for the manifold air temperature sensor, check to see that someone hasn't left it unplugged after taking the intake tube off.
p0443 is for Evap emission system purge valve/solenoid. The purge valve is a pulse modulated valve controlled by the computer. It turns on and off allowing vacuum to suck in air or gas vapors from the charcoal canister up into the intake. With the correct scan tool you can command the valve to turn on and off (modulate) and see if it is clicking on and off. you could hook up a vacuum pump and gauge to see it the valve is opening and closing. Something to check for when you disconnect the line from the charcoal canister is if there is any grit in the line. If there is the charcoal canister may be bad abd bits of charcoal are coming up the line and holding the valve open.
P0449 is for the evap vent solenoid. This solenoid is similar to the purge solenoid in that it is controlled by the computer and clicks open and close to allow air/fuel vapor to flow. It is just at the other end of the system.
You should look at your fuel tank pressure sensor (FTP). See if the fuel tank pressure sensor is working correctly.
there is no separate fuse for the Intake air temp. it is a two wire sensor and both wires go to the computer
