1990 2.3l high idle problem

well i have always had a high idle around 900-1000 and now its around 1250 it does come down as the engine warms up but it still stays around 1000 (this is all in park) when i shift into reverse or drive it will be around 750. which is what my car should be idling at "correct me if im wrong". so i really dont know what it could be

I don't know if this helps or not If you have an Auto, It should be between 800-900 RPM in park and between 700-750 RPM in drive/reverse. I've had the same problem and what I did was just turn the screw down on the intake till I got it were I wanted it. Did that a few years ago and never had that problem since.

It is what it is.
