Where and how do I adjust the throttle / idle ? My 1994 Saturn Sl2vis racing after hitting construction barrells on highway at high speed ! Minimal body damage ! But has been racing since!
SOURCE: 2002 saturn sl1 idle too high
Can be but also check and make sure there are NO vacuum leaks or broken vacuum hoses anywhere on intake. I would also suggest if engine light is on is to take this vehicle to an AUTO ZONE they will check by computer for this problem and let you know for FREE. When you get the code I would be more than glad to help you further. Don't guess you may be wasting money and time. Good luck and thanks for using FIX YA
SOURCE: Saturn 1999 sl Engine has a high idle speed.
The Idle Air Control valve is located on the throttle body. If you follow the intake tube from your air filter all the way back to the intake manifold, where the intake tube connects to is the throttle body. Remove the intake tubing and you can see the throttle body.
There are two sensors on the throttle body and a vacuum line. You'll see two harnesses going to the throttle body, one is the IAC.
However, a quick diagnostic check can be done without touching the throttle body to confirm your problem. If the car has a normal idle when initially started but then rises to a higher idle and stays there BUT then if you were to shut the car off and restart it and it comes back to normal that is the Throttle Position Sensor (TPS). This is also located on the throttle body (the other sensor to the IAC). If it is the IAC it will be high and maybe fluctuate a bit.
Testimonial: "I was the one who listed this problem. Thanks a TON for the info. Now, I'll try to fix it. The ultimate check is if if idles normally."

No..you can't adjust the idle...
Possible cause---Electric throttle control actuator, intake air leak or PVC system...check these 3 things...
