The Gen II 3800 Engines have a HORRIBLE ISSUE with the INTAKE. They are made from Plastic and Warp. Waiting for the Engine to Get Hydro Locked (Coolant in the Cylinders)
The code indicates the TPS is still bad and the code is usually right, but it could be a wiring issue at the TPS connector or less likely a computer issue.
To test the TPS circuit, you need to check voltage and ground from the ECM - 5v is the normal reading between the ECM reference circuit and the ECM ground circuit at the TPS connector. Checking the TPS signal circuit to the ECM requires monitoring the TPS signal on a scan tool while jumping the 5v reference and the signal circuits. The TPS reading should go from high when the circuit is jumpered to low when the jumper is removed.
Make sure the battery cables are clean and tight on the battery. Check to see if the wires to the starter are tight. Try starting it in neutral to make sure the safety switch is being make. Also hold it up into park and try.
Look in the trunk to see if there is a round cover on the floor of the trunk. If there is then you'll have access to the sender. If not, then you'll have to drop the tank to get to it.
The L67 motor in the park ave ultras use a Eaton m90 supercharger. The coupler in the noise cone will go bad. Try replacing the coupler. Can usually purchase one for 40.00 from a shop that rebuilds them. Hope this helps.
