2001 Chevy Tracker 4 cyl Four Wheel Drive Automatic

My problem is, when you travel a distance, or if you have to idle in a drive-thur and then go to take off it will start to miss and quit. It is very hard to get back started, if you keep trying it will backfire thur the air filter and stink, then if you get it to start it will miss and sputer and slowly start to run right. If you have the time you can let it sit for about 20 minutes and it will start back fine. We have done replaced the starter and the o2 sensor. I hope you can help me. Thank you for your time.

Disconnect the idle air module and take it for a drive.

Does this cure the problem?

The module could be bad a common problem.

Have you ever replaced the spark plugs or plug wires?

Yes, we have changed the plugs. My tracker does not have spark plug wires, they said it has spark plug sensors.

Could be the fuel pressure lacking. Your going to have to get it to die at home and when it wont start check the pressure and check for spark.

I have a 2001 Tracker and mine does about the same as Lanier's tracker but mine stalls out after sitting at a idle for a few minutes, if I try to start it right away sometimes it starts and sometimes it don't, but when it starts it pops and sputters and smells like rotten eggs, won't run right or keep running unless I play with gas. But if I keep truck off for about 5 minutes it starts ok and runs like nothing happened. Been told to replace thermostate(waiting for one to come in after ordering one) and clean the Trottle Body housing with trottle body cleaner which can be all black inside(which I did) but same thing still happens to truck. Any suggestions?

Stalling is mostly due to a fault with the idle control system and the first thing to do is to check for trouble codes even if the Malfunction Indicator Light is not showing. Some codes do not trigger the MIL whereas at times it comes on and then goes off. If any trouble had been detected by the Engine Control Module, the code would be retained in the ECM until it is erased.

Start with a scan first. If no codes are found, then the following might help.

Stalling when hot could be due to low idling speed.

Stalling during cold start can be due to the above and/or you have a fault with the cold start system. The engine does not increase in speed during cold start thus the stalling.

Disconnecting the battery would also results in such problems as the computer needs to relearn but is hampered by a dirty throttle.

A dirty throttle body restricts/reduces air flow through the idle control system and this affects idling speed usually resulting in stalling when accelerator is not depressed.

Usually cleaning the throttle body and related components solves the problem.
