Definitely need driving data. Though I’m not sure how much WOT you should be doing with the issues you’re having, I think that will be the most beneficial.
Gonna give it a shot in a few days. I just found the outer tie rods in the truck that numb nuts never put on. Then it needs tires swapped and a wheel alignment.

I think I can record Luve Data with the scanner I have. Would that help? Would I need to record while driving it? Or would idle be fine? Thx for any help Scotty.

you should be able to see live data driving, see if you can find Knock Retard and timing advance as well. if its got KR thats a feeling weak issue due to timing being taken away. how the pcm trys to protect the engine from blowing up on ya.

also see if you got the o2 sensors bank one sensor one, bank two sensor one in (MV) idle and normal driving its gonna bounce around some, but wot the o2's should lock in around 930 ish and stay there while wot the whole time. if one is dropping or reading low, basically a lazy o2, this can cause fueling issues like running lean. and lean can cause KR.

X2 need to log KR and spark advance so we know if it has no timing or some crazy reading
