Okay here is a recap, Okay with the PowerKey off and after a 20 or so minutes of driving my check engine light turns on. Prior to the check engine light the car runs just fine through the rev range. Once the check engine light turns on when I use throttle past 3000 I have a very strong stumble or cut off. And with check engine on or off I don't have my secondaries opening. I check the pump is working and yes it is, and the codes I pulled are 52(Pass-key key detection circuit shorted) and 61(Pass-key – key #1 programming resistance out of range). About 200 miles ago I just completed a extensive under plenum rebuild the link is below of everything that I did. What is my next move gentlemen.
