Engine Performance problem
1988 Dodge Ram V8 Four Wheel Drive Automatic 170 miles
I have a 88 ramcharger with a rebuilt 318 engine (about 35000 miles on it)with a throttle body.
After starting it hot or cold the idle races up and will not come down.
the idle speed motor seems to be moving, but very little.
The egr valve has about 50,000 on it and I pulled the vacuum hose off it but did not see any change in idle speed. The map sensor is 3 years old.
Any suggestions as to where to start?
have the same problem?
