I discovered that the previous owner set the ignition timing on my prizm without the diagnostic jumper connected, end result is that the car was at 4 degrees BTDC with the jumper connected when it should be at 10. Now it idles at the 16 degrees BTDC vs 10 it was. What kind of FE gains should I see?
