97 Idle Problem
I did a search and there doesn't seem to be any posts specifically addressing the problem in a 97. After a 225 mile drive home yesterday in driving rain I got in last night and in park and neutral it will idle around 1400 rpm and in drive around 1000-1100. Today I did a quick errand and it did the same for about 3 minutes then settled down but didnt on the way back. It sounds from reading that it could be any number of things. Should I look at the stepper motor first? IF so how much does one cost to replace?
Also the truck has a supercharger, could this be the issue?
