FAST IDLE Adjustment. 3,000 RPM's eeekk!

Feb 10, 2004 Last reply: 17 years ago 2 Replies

My GF's 1998 Saturn SW1 needs the fast idle adjusted, when cold, it revs up to as high as 3,000 RPM'S Way too high. After about 30-45 seconds of warm up, It slows down to a normal 800 RPM or so. Are there any specific steps I need to know? if not, where would I find the adjustment screw? I want to make sure I do this by the book. It has 50,000 Miles and the only maintenance I know of is the serpentine belt change. So IM assuming the plugs and other tune-up items haven't been changed



Ill be doing a tune up on it in the next few weeks. Plugs & Wire set Rotor (assuming it's NOT distributor-less) Gas filter Air Filter Radiator Flush Transmission/Transaxle flush (Or is this FWD tranny sealed? requiring no maintenance?) Any other maint. tips?



sorry, this car is new to me... lol :) Any help is greatly appreciated!!


SORRY FOLKS, I POSTED TO WRONG NG shame on me..

By personal experience, have a simple answer to your question. CHECK THE BATTERY...My 200 Saturn SL was doing the exact same thing for the last 2 months. I the last 2 weeks, I was getting a "service engine soon light, and just recently my battery completely died. I replaced th battery, and the problems went away immediately. Rational...Saturn have a finicky electrical system. My family has had 6 Saturns, an every time the battery dies, it always seems to go without warning but I have discovered that it is because the cars have been designe to compensate for batteries that are dying. And, I believe that th

3000 rpm idle is part of that compensation (works the alternato extra to cover the low power). My 2001 Saturn was at 138,000 mile and 8 years when this original battery finally died. In summary extremely high idle?...Check the battery...Simple $65 fix
