When I did the cal mod to my sensor it seemed to help the chuggle at 40 mph although it did not eliminate it completely. It now downshifts easier rather than holding the gear.
The old TPS has been thrown out, and the new one elliminated the code, as for the ignition wires, I just checked and #2,4,&6 wire and they are not touching the O2 sensor I also I could not find any arching. The wires on it now are AC Delco, but I also realise that my diagnoses doesn't mean that the wires are still good. I will order new ones, but in the mean time, could it possible be anything else?
