I replaced the head on the my 2.3L quad grand am and i seem to have forgotten where one of the cords connected to. I started the car up and it reved way too high than normal.
Welcome to the forum. Is you engine MAF'ed? If so, it sounds like you didn't plug in the MAF. If your engine doesn't have a Mass Air Flow sensor, then it could be either your Throttle Position Sensor or Intake Air Control motor are unplugged.
