Engine stalls at idle?

Car hesitates sporadically, have recently unplugged the air temperature sensor, found that unplugging it exacerbated the problem. The car stalls when I come to a stop and have the clutch pressed in. It hesitates when I step on the accelerator. Have narrowed it down to something electrical, I think. It comes and goes very quickly. Since I have replaced the temp sensor and it has not solved the problem yet, what is connected to the temp sensor that could cause it to malfunction. What potentially could cause the car to sporadically hesitate given the symptoms?

I have an 02 also with 75,000 miles. My car has only done this twice but it will idle okay but if you give it any gas it will bog down. Also is you idle high 1500 rpm I have read that the Air temp sensor can cause the idle issue. We my have the same problem but mine has not progressed yet. If you found a fix please let me know.

I have a 2001 Chevy Tahoe with 87,000 miles. Within the last 4 to 5 months the SUV has been stalling will at idle or turning in a parking lot. It runs good while driving at a constant speed. However, I do notice the car surging or the RPM jumping as we are traveling. On long trips (250 miles) with AC going, at the end the check engine light will illuminated for a couple of days then disappear. This only happens on long trips. I have changed the fuel filter, air filter, PVC valve, and battery. The only thing I have not changed is the spark plugs. The last couple of days after getting the PVC valve changed the car has died three times each day. I can place the car in neutral and it starts right back up again. Do you have any ideas or suggestions? Thanks for the help.

Just bought this truck, replaced fuel pump, filter and drove it home, replaced steering column and now the truck will not stay running.

Yes the battery was disconnented

How do I get the computer to relearn the idle if the engine will not stay running

Good evening! Today I have noticed my truck now wants to shut off when I come to a full stop. If I start it, it will stay running also as long as my foot is on the accelerator the truck will run. Whenever I go to stop it stalls. Always starts up pretty much right away. The only code I have showing is a po157 which I know is an oxygen sensor. I have had that code on and off for the last six months. Although, I plan on replacing it soon I do not picture that being the reason my truck stopping. Any ideas on what to look for first I would appreciate it? I did look at the wires tonight they do not seem cracked. I also took a spray bottle and check for vacuum leaks. I also sprayed around the spark plug wires to see if it would shut off if there was any kind of moisture in the cap and rotor which nothing happened. The only code that keeps popping is the po157. Do you think this would cause it to stall because of the air mixture or do you think it is something else? Any help would be appreciated.

The fuel pressure reading was 60, changed out the idle air control valve, still won't stay running, but it does fire. Would any of the wiring on the steering column cause it not ot run. Check codes and nothing.

Thank you. I am at work now, but I will look into it when I get home and I will let you know.

That did not seem to do anything. The truck still runs the same. Also, wanted to give you a heads up if I have it in park and I rev the engine nothing that happens does not shut off keeps running. If I put it in reverse and pull out of the driveway and put my foot on the brake it shuts off so it only seems to do it when it is actively driving otherwise if I leave it running in my yard it will run even after I rev it many times.

Truck was running fine, no problems. Stopped @ store, started truck & it run about 10 sec. Then quit. Tried starting again, same thing. Repeated starting over & over till battery died. Towed truck home, tried again & same problem ! Help & thanks.

I have changed the ignition control module, the crankshaft position sensor, the fuel filter, the air filter and the distributor cap. The fuel pump tests out at 65psi solid. I have check for vacuum leaks and tested the coil it was fine.
