So today after classes my car was running in safe mode. It wouldn't go over 3000 RPM's. I tried to pull the code and it didn't do anything when I stuck the paper clip in the socket. So I tried to reset the ECU to see if it helped and it idles funny. Rises about 200 RPM's then drops to 1000. It does this over and over. I tried pinching off vacuum lines to see if it would make a difference and it didn't. The funny thing is it was fine on the way to classes this morning. Any ideas? I'm stumped..... another thing is I got some gas yesterday.
