My 92 GMC suburban is having issues at idle. It just started yesterday when I went to start it to move it. Didnt want to start, unless I gave it a little bit of pedal input. Then when it did start, I wanted to idle at 500rpm or less. Stalled out a few times. But finally got it to idle at around 6-700 ish. Then I took it out for a ride around and it runs and drives fine. Everytime I let off the gas though, it wants to idle down immediately. Then I got back and parked it and shut it off. Then I started it back up to see if it would do it again, and then it was idling between 1500 and 2k and wont come down. So I shut it off and started it again, and it did it again at high idle.
Doesn't seem to have a happy medium right now.
Other wise the engine is running well. Sounds smooth, throttle is snappy, no stumbling. Just idles to low or too high.
Any thoughts?
