Bad and/or worn out spark plugs could do that. The coils and ICM interact so one can damage the other.

I have been there with this problem. I have the 2.4 so its different, but my ICM was bad so it was causing my coil housing to go out.

I have the same Cavalier, and replaced the coil pack, and the ignition control module in mine 9/08. I had the ICM replaced in 1/09 again. Engine light came back on two weeks later. I'll have it looked at, along with the coil pack. Doesn't make sense to me, but I don't understand the electrical end of cars at all.

Dear rearroo3-- I think the alternator on your 2003 Chevrolet Cavalier might be sending out to much power to these components. I had a friend with a similar problem redently, but instead of the ignition module and the coil, his car sent to much power to all his lights and he burned out bulbs weekly- on a car just a couple of years old. With electrical problems I always recommend consulting a professional mechanic. One wrong adjustment and you could have serious (or more serious) problems. Have it looked at. Good luck from Bovan.
