Drove away from the gas station without replacing gas cap, not sure if that was related to problem. After a few blocks, check engine light came on. Closed gas cap, but engine began running very rough, light remained on. Had check engine code diagnosed, was told that coilpack had failed - had to have it replaced.

I have had this car a year now, not even. Put about 25,000 miles on it I am on coil pack #3 and module #6 from the zone. Car has been to 2 private shops and a dealer, No one can find anything wrong causing this. Now I have a misfire at 3000 plus RPM. Here we go again.
It would really be a nice little car without this grief.
