high idol

[shaner123]

hi, i have a 2001 SL 5spd. OHC, and ive been getting a high idle quite often, its around 1500, and normailly its at 800ish, my understanding is that saturns have a moving idle speed and a stoped idol speed? im not sure, ive cleaned the EGR with carb cleaner(it looks good), replaced the PCV, and cleaned the throttle body with carb cleaner, and i still get this my theory is that my car is getting confused and thinks im still moving when im sitting at a stop in neutral, but i dont know, im going to clean the IAC tomorrow, but not sure thats going to help


thanks for any help

the later SOHC 1.9L engines tend to suck in the intake manifold near the #1 intake runner, hence resulting in a vacuum leak. spraying the carb cleaner in the area of the #1 runner will confirm this, if you have a leak the RPMs should drop.
