2000 Saturn SW 2 has a high idle problem

Hi HwnBoi, You could have a problem with the throttle position sensor reporting incorrectly. I would also have your computer scanned for any trouble codes (like an O2 sensor) that would produce a lean mixture. Good luck!

mine acted up only once and awhile after being drive 20 plus miles. when I came to a stop the idle would go up to 28-3200 rpms. if I shut the car off then turned it back on it would b okay. it was the idle air control valve. once I pulled into a parking lot and the car was revving high so I popped the hood and tapped it with a wrench and the idle returned to normal. replaced it for 35.00 dollars and it has been fine for the past year and a half.

Hey does 2000 Saturn S-Series have a timing belt or chain

Has a chain all Saturns have chains only.

i love these sights for the info i too own a 2000 saturn sl2 and have been struggling with highidle problems i think i may be on to something about this. i have replaced sensors cleaned the throttle body replaced t-stat and temp sensor checking electrical connections is what may be the problem mainly the ground there is a grd. strap at the PCM it was corroded i cleaned it and 2 others on the block 4 days with out a problem give it a try its free maintenance and worth a try good luck
