Hey guys right before i put my car away for winter i was having this problem with a miss fire or something to that nature, when the check engine light would come on the problem would stop. When i got the light checked they said it was a cylinder one miss fire, but as long as the light was on the car ran normal.... I just pulled the car out for my florida trip and it was miss firing like crazy, so i changed the plugs, and cylinder one plug was black all the rest were fine. After i changed the plugs it idols better but still miss fires the hole time, when i drive it the check engine light flashes on and off, it is really wierd! I need help, anything ever have anything like this?

Thanks Travis

Hey guys it looks like after reading every one elses problems it sounds like i just need to change the coil pack housing... where can i get one?? how much? Um everyone else was talking about cylander one miss fire but when i pulled the plugs the one on driver side was black, i don't know if it was built up fuel or just burnt, but i was just wondering because on my car everyone said that cylinder one is on the passenger side, but idk....

By the way i have a 02 2.2L cavalier
