Some new data.

Decided to LOG pretty much everything. It all looks Kosher and perfectly normal. The bucking is getting worse. No oil consumption, no external strange engine noise, no smoke out the oil cap, or exhaust.

I just dont get it. The car hasn't thrown a CEL but is nearly undrivable under load. Knocking has pretty well stopped due to IAM at .650 (i assume bucking is due to lack of timing)

Havent tested the knock sensor....but I should see the problem in the data. I see f%$* all.

Experts.....replace knock sensor? Burn car to the ground? Fuel trims are complete INSANE!
