DING DING DING!!
Marty is right. It was missing... I pulled another code when i got home and
the first one went away... P0357 i think which means the 7th coil is
malfunctioning. Broke the tools out, had the coil pack nut mostly off when i
realized the clip-in coil wire was disconnected! Impossible!!! I checked
everything so many times before i even drove it... It had to have just
barely not clipped in... even though i am so truly careful when i do
anything to my truck.
Click!
Zrrrrp...Tic-Tic-Tic-KrrugghhhVAAAAaaarooOOOOooom!
Runs like a beast. Huge improvement over the last plugs, i can tell and i
haven't even broke out the G-tech yet. Much smoother, quicker revving,
stronger pulling.
Thanks for all who tried to help out!
