i get gas , only 10 bucks worth, which fills to a little passed half, im driving home and im backing up my driveway which is on a slope , so i stall out, and start it back up and my tank is pinned at full, u may say it was because i was on a slight hill but i was on it for about 1 second when it stalled, i drove around , and drove around and it slowly slowly went back to where it almost was, it was actually pinned on full for a while, anybody have this problem????
