Re: High RPMs
Newbie here, but I had the same problem. Had built in cruise control between 25 & 40 for blocks at a time. Reved up to 3m or 3500 on start up until I put it in gear and then 2m until moved down. Reved between 1500 and 2m when at stop. My son, after many parts that didn't help, put on a ?? selenoid. It's located just to the right of the throttle body and under the air filter housing and pushes the carb butterfly open. The plunger was staying open and SLOWLY closing. My 1990 in all the books except at NAPA said I didn't have one on my car, but it was there. It worked. Check it out.
