gormine

For the past few months my car has had this problem. About 80% of the time when I come to a stop and idle, it will idle at about 1300-1500. I can get it down to 750 by blipping the throttle to about 2500 and letting it fall down. It don't work all the time but 90%, just takes a couple tries sometimes. I have tried lubricating the throttle cable and linkage springs etc. What else could it be?

mine does this on occassion if i start driving the car cold without letting it warm up a little first. not sure how to fix it. normally i just let the car warm up a little.

I always try to wait at least 5 mins... at the least i wait 3... this happens all the time though.. 3 or 20 mins of warming up.

Nobody else ever had this problem?

It looks like you have the mechanical issues covered.

Here is one the sneaks up on you - grounds.
The sensors all work with weak low voltage signals.
Fixing or replacing grounds, especially the one from the bell housing to the firewall, can fix many different problems.
Many have had amazing improvements by adding a ground or two.

I have the problem too and I think it might be a gummed up BAC valve. Try cleaning that out.

I got this same problem, just wandering where I should add the grounds? Just everywhere?
