Automotive/Possible Idle

Expert: - 2/8/2010


Question
I have a 97 saturn, basic stick shift. I believe it is the idle, just not sure. For some reason, the RPM never goes down now, is it the idle? The car has 148k, still drives good even with this. Do you believe it is the idle?

Answer
Kris,
  I'm a Parts Specialist, NOT a Tech. This is explained in my Profile but will give this my best shot.
  Your question is confusingly written. I'm not sure what you are asking but I would guess that the engine will not come back down to a normal 500-600 RPM range??? You don't tell me what RPM the engine idles at???
  Obviously there is an Idle problem. I'm not sure what you mean by "Do you believe it is the idle?"
  Going out on a limb (I'm not a Tech), I would run a vacuum check to see if the Engine Vacuum is in the 17" range. If it isn't, I'd look for a vacuum leak. IF it is, I'd look at the Idle Air Motor or, another name is Idle Air Control Valve.
  Sorry I'm NOT a Tech but I hope this helps a bit and gives you direction..

Heretofore, I will NOT answer any mechanical question. I am not qualified and can only offer speculations. You are better served by others that are true Techs. With that being said, please only ask about parts and locating obsolete Auto Parts. Thank you. I have the ability to locate quite a few mechanical parts for American made vehicles fron the 1900`s to present. Some are OEM and some are aftermarket. This would include engine, brake and chassis parts. Body parts and trim are VERY difficult to find but you may inquire. If you need assistance in repair, I have illustrated books for major American manufacturers that show some illustrations BEFORE 1974. If needed, I can supply repair manuals for your specific vehicle. PLEASE REMEBER I'M A PARTS SPECIALIST, NOT A TECH!! Thank you.. Skip
