    I have the same problem on a Saturn 2002 SL1 manual. I've replaced the IAC, PCV, and TPS. I'm still getting idle levels between 2,500-3,000 RPMs. The car runs fine other than when idling but it gets really loud at every stop light!! Any solutions? Also, readings tell me error codes P0301 and P0507. Those translate to cylinder 1 misfire and IAC idle speed higher than expected.

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

They make a connector for the sender unit and they have to usually be replaced. Watch which way it goes on since they are a little cumbersome plugging back on...I prefer soldering the new connectors on too.

I have a Saturn 2002 SL1 The RPM remain at 2500-3000 RPM when shifting gears. After abotu 30 seconds the RPM will come down to 900 while sitting at a light. What would be the best place to start chasing...


Sounds like a dirty IAC (Idle Air Control) valve. It is located on the throttle body. Remove it and clean it throughly as well as the throttle body underside as well where a lot of carbon build up is.

However, since it is such a high idle, check for any vacuum leaks. Check your hoses and lines running inside the engine bay, specifically near the intake. Spray some carb cleaner around while the engine is running to see if you can hear or see a leak. Check the intake gasket as well.
