my car is Chevy Cavalier - 1999.the car would start, but as soon as I put it in gear, it would sputter and stall. If I got the car up to speed, it would run and I could drive it, but it was still bogging down on hills and was very difficult to get up to speed from a stop.My mechanic replaced the spark plugs and wires but the engine still gave misfire codes. He then replaced the ignition coil and it solved the problem. the problem came back after a week. I did not notice any problems with the car up until this morning when I tried to start it up. It did start and I was able to drive it to the shop again, but still had the same problem.He said that if it happens again, we could look at it and see if we could figure out what is frying the ignition coil. It is only happening to the coil for cylinders 2 and 3. What could possibly cause this to happen? any help is highly appreciated.
