Engine Performance problem
1999 Saturn SL1 4 cyl Front Wheel Drive Manual 76000 miles
The check engine lt. Is on, code 507. The idle speed goes up to aroun 2000rpm on start up for around 20 seconds, then drops to around 1200. If I accellerate at all, it goes back up and repeats the same thing over. The idle speed stays up between shifting as well. I know there are a number of sensort that can cause this code, any suggestions where to start?
