There is not much information here because different automobiles can the same symptom with a totally different cause. Giving it my best guest I would say that you have a leaking fuel pressure regulator the engine can handle the extra fuel when driving but run much too rich when idling.
What causes back firing on a ford explorer and it to idle rough and want to cut out when you try to give it gas.
I would suspect a faulty fuel pump or fuel pump relay.
Check the 92 Eclipse for vacuum leaks. Check to see that all of the spark plugs are firing properly. Check to see that the fuel injectors are working. Either of these could cause the rough start and rough running.
The issue sounds like engine timing may have jumped. Check the time, also check engine codes for a possible sensor malfunction.
my trac off light comes on in my 2002 cavalier then the car cuts off, but will start back up minutes later then the check engine light will come on and they both stay on
what could cause a car to run for 20 minutes and dye and waiting about 5 minutes it will start back up and run for a couple of minutes and then have to wait and it will start back up and go for about 5 minutes and dye again. Chevy cavalier 2004
Timing is way off or spark plug wires incorrectly connected.
because the engine is cold. after it warms up the light goes off. Cute! But what causes the blue light to come back on even after you've been driving for a while?
A dirty fuel filter or fuel pump failure.
I have the same car. Mine doesn't start sometimes. It does not start after I have driven for ten minutes or so and stopped and turned off the engine for about 25 minutes. It will start immediately after it is turned off or ten minutes later, but not 30 minutes later. I have to wait about an hour or longer for it to start again. If I turn off the engine, then run back to the car every ten or fifteen minutes to start it, it is fine. I also think it will start if I turn on the ignition for 30 seconds or so before I crank it.
Disconnect the battery cables for 15 minutes. Then put the key in the ignition and turn it as if to start the motor, and hold it in that position for 30 seconds. (This resets the computer, codes, engine, everything.) When powering it back up and running the engine, it may run slightly rough for the first few minutes as the motor resets and re-samples all systems.
the thermostat is likely sticking
