what did you swap? Pulled all the Renix and replaced 100% with HO sensors, ECU, etc? The Renix TPS requires some adjustment, if you still have that, I'd check that. Not sure what to do with an HO TPS, other than check the voltage at idle and WOT, google to see aht it should be. Tranny issues could be the TV cable (the one next to the throttle cable). The adjustment on that is pretty important for proper AW4 shifting, it sets the line pressure in the tranny. Hard gas pedal could be the throttle cable...is the bracket where both cables go firmly bolt to the intake manifold?
