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.

Why won't a 1994 Oldsmobile silhoutte start until after the steering wheel has been tilted a couple of times?
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.
How do you reset the 'Check Engine' light on a 2001 Ford Ranger?
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.
