I have a 2002 Bonneville SSEi six cylinder with a super charger. The car was running rough so I took and repair garage and they gave the car a tune up. When I left it was running smooth. The next day the car was running rough again. The mechanic stated that the computer said mis fire in cylinder one. He change the distributor. The can ran smooth again. The next day it was back running rough. On the way to the garage it smoothed out again, so I went home. Now it is running rough again. Any clue what the problem could be?
