to reset your ECU, either d/c the batter for 10 - 15 mins or unplug the plug to youe ECU under your scuttle pannel. Once you are all connected back up again, you need to leave the ignition in auxilery for 2 minutes while it sets the throttle up properly. once that is done, turn off, and start, the ECU will then re-learn all it's settings again.
