3 out of 8 coils seem to have issues upon tearing into the truck. #2, #3 and #6 are the problem children. #2 is not firing at all, #3 has weak spark but operates normal upon 2,000 or < RPM's and #6 wants to heat up to 210 degrees while all other coils is 73 degrees. Needles to say I will be replacing all 8 coils if I don't just trade the damn thing in to the dealer
