i noticed this weekend that when i floor the accelerator, the throttle does not open all the way. if you push it open the rest of the way, with the pedal still floored, it will stay open. i tightened the throttle cable as tight as it would go and still allow the throttle to shut. i also ground the back of the pedal to allow more travel thinking this would help. it did not. is this a problem with the geometry of the pedal or the connecting bracket for the throttle body and the throttle cable? anyone else experience this problem?
