2002 Saturn SL idle too fast 2500

\015 I have replaced the idle control valve and the throttle postition censor and it still idles at 2500, it's a 5 speed manual transmission. What else could it be?\015 Posted / edited by AnonymousUser on : 23-11-2020

Answers :

More than likely its your Engine Coolant Tempature Sensor (ECTS) sound strange but its a common problem with saturns the part cost from 10-20 dollars and takes about 15 minutes to do
Just sounds like the throttle body valve is not closing all the way, possibly stuck a bit from some type of build-up, it may need a clean

if this doesn't work you should be able to adjust the idle manually by taking a screwdriver and backing down the idler screw which is located on the throttle body that closes the butterfly valve inside
