93 Buick Park Avenue/Engine revs when shifting to park/High idle rpm. What is wrong and can I keep driving it?
Ok just bought this 93 Park Avenue. And there is definiltly something wrong with it. Here's the syptoms:

1. When shifting into drive, from park, the engine quickly revs up to 2k rpm, then goes back to Idle 2 seconds later.

2. The car idles high, at about 1200-1500 rpm at all times.

3. When drive, if I'm not touching the gas at all the car has a really fast "crawl speed". I cruise down the road at 25-30 mph without even touching the gas. Also, if I build up speed, like say to 60 mph and let off the gas it stays at that speed, as if there is cruise control on.

4. Whenever I shift from drive to park or neautral, the car revs up to 3000 rpm on it's own and STAYS at 3000 rpm until I turn the car off or shift back to drive.

Any help/comments/advice is appreciated. I just want to know what's wrong, and if it's ok to keep driving the car, or will this get worse and possibly cause more damage to it.

Do you
have the same problem?
