Thanks, I was thinking of the coil pack myself, however the shop feels confident its not the coil pack as it "tested" good, plus according to their head head mechanic if the coil pack were to be bad, it would cause a misfire on more then one cylinder, just not number 3 cylinder only. Don't know if that is true or not.
