I just wanted to post this out to all the people having problems with their cars with some of these sypmtoms. My idling would always idle at 1500rpm(warm and cold)and bounce only a couple 100rpms, then I tightened the white thing on the Fast Idle Valve and the bouncing had stopped. A month later… my car dies. The engine would crank but would not start, I found out that it was the ignition coil. I got one for $57 @ Kragen… After that it started right up. The feeling after that was really smoother and faster than it was before. I never got to fix the high idling yet though, I have a code 7 (throttle position sensor)… But after the coil was changed the idling went down to around 1100-1200 rpm. So if that helps anyone then good luck…
loosed your throttle cable, your throttle is not going all the way to 0% when it is released. If you look right on top of your IM you will see a cable running across. You need to loosen/tighten the 2 nuts in order to correct this problem.
HTH,
Mike
that wasnt my problem, i found out that i had the code from when my friend unplugged the sensor, anyway that was a while back…
