What's up Franke...
I did a few laps around my neighborhood, then 16 miles round trip to get Safety Inspection - that's a go, no problem.
Hesitation, observable under light throttle, is NOT gone.
The same hesitation that's evident at LIGHT rpm increase from idle is (and was before) evident in Reverse, and in Drive. Under light throttle, it is (as was before), evident as it shifts, and begins rpm climb again.
I cannot accept a vacuum problem, or mechanical problem. It HAS TO be electrical, related to the auto controller module, and the circuit that's singing, as TPS BEGINS range of motion (the 'singer', is in the tranny). Tranny controller diagnostic shows no tranny controller codes. Tranny shifts perfectly, and responds to changes in setting as well.
Everything NOW, with the 'Primary Only' gasket in place, is the same as it was before the plenum pull, with secondaries operational (except for the dirt).
And the Cruise lope, although I didn't engage Cruise, I'm sure is still there, and I'm certain it's also related to the hesitation / TPS circuit.
