After changing battery, 1997 Saturn SL-1 idles at 2,500 RPM
The ECM maybe stuck, disconnect the battery and wait 5 mins then reconnect.
Other things that normal cause high rpm at idle:

Pull the engine coolant temp sensor, I know it sounds funny but do it if your looking at the engine it is located on the right side of the head.. chances are the ceramic tip on the sensor is cracked.. 15 dollar fix or so should take away from the high idle.. let me know how it works

Solved my problem: After more internet searching and consulting with my mechanic we determined it was the intake manifold gasket folding over into the #1 cylinder. This is common on Saturn engines. The gasket folds over leaving a leak in the vacuum system which causes the car to run lean. Check for a leak by spraying carburator cleaner around the #1 cylinder intake and you will hear the idle change if there is a leak. I had gasket replaced for $450 and car runs like new. My car is a 2000 saturn SL 1 with 60000 miles on it. Hope this helps someone.
Testimonial: "Thanks it really worked."

Hello DTC P0341 & P0133 very common saturn Codes.You need to check condition of Plugs & wires,If not New Replace All Plugs & Wires,also I would replace the #1#4 Coil for the P0341.For the P0133 Reaplce your front O2 sensor with an OEM sensor,not an aftermarket.
