Dragonbag,
Very respectable post! I appreciate you not jumping to conclusions. If you have time, give me a call at the shop....I have a good idea of what you may be up against. I need a bit more information from you first, but you have already checked some of the things I would recommend:
Plug Caps and Wires
Stock TPS calibration
PCV to TPS synchronization
DET Sensor
Injectors
Pistons and rings
ECU
If it really is only one cylinder, it is more than likely not a pipe temp sensor or DET.
I look forward to hearing from you,
Dustin
Just got off the phone with Dustin from SLP. Very knowledgeable guy. He is going to hook up with my dealer and work with them to resolve the problem. Very much appreciate the extra help! Thanks Dustin!:face-icon-small-coo
