In the 5 times that I pressed the brake it probably went up about 500rpm. It was at 900 when I started, and was at around 1500 when I stopped.
Also... I tried resetting the ECU... didn't work.
Disconnect negative cable and hold in the brake for about 30 seconds, right? I did this and the CEL was on as soon as I started the car. Am I doing it wrong?
