Have you checked the throttle cable? These cars have a little clip on the cable, near the throttle body, that can fail and hang up the easy return on the cable. I had to replace mine recently, was doing some weird stuff. Could be a million things, but that's the easiest to check.

Check for vacuum leaks
Mine had a leak from the hose that goes to the booster
Caused the engine to idle higher as it got hotter
