Hope that helps
We check out TPS signaling was .3 to 3.9 (spec is 0 to 5) so seemingly ok. We swapped MAF and it helped a bit.Our condition has gotten weirder. It now comes and goes. Swapped IACV and thought it solved, nope back in AM on startup. Dove 200 miles and idle condition is now fine. Still no assignable cause.
