I have had this issue for a week or two where my engine will idle at 2000 rpms instead of the normal 700. When I shift into "drive", the rpms hang around 1000. Sometimes it goes back to normal after driving a while.

I took it to the dealership, but the problem didn't occur when it was in the shop (big surprise there!). They said it could be a dirty throttle body or injectors. There are no CEL's except for the power steering pressure switch, which I just received and will be changing when I have free time.

Any thoughts on what the problem could be? I tried runnning premium gas and some injector cleaner, but its still happening.

Ok, I gave the throttle body a good srubbin'....and the problem still persists.

A buddy at work is gonna give it a look for vaccum leaks by using SMALL amounts of ether, then listen for the engine to rev up.

As for slack in the accelerator cable, I will give that a shot too. It seems as if the throttle likes to hang open now too. I noticed that when I am braking, the engine will stay revved near 1K until I am at a complete stop.

Nice to hear progress!! I'd grab a brand new one to be on the safe side though. I think autozone has them for like 60-65 bucks
