My car has been having idle issues which I just noticed. It will idle then the revs will nearly all drop and it will seem like the car turned off but then the car will shake and pick up revs again and repeat this. This is a big hassle because when I stop at a stop light, 60% of the time my engine will just turn off due to these loss of revs. I checked the FAQ stickies and it said my TPS needs adjustment. I don't know if it's really the TPS though..

I came home from work and the car hasn't been on since 2PM, I got home at 9PM. I started it up and sat in the garage for 30 seconds, there was no idling problem. I drove down the street and stopped at the intersection, the car didn't stall when stopping and the idle was normal. After I drove around a few times and the engine warmed up(2-3 minutes of driving), the idling problem returned. I revved the car and the idling problem again disappeared but only for about 5 seconds this time.

 

These threads pop up on a daily basis:

You read right in the FAQ. Check TPS. Set the idle speed after checking TPS. Then check the Bypass Air Control Valve (BAC) which is responsible for your idle.
