Must be contagious. I just pulled the code:
P0222 Throttle/Petal Position Sensor/Switch B Circuit Low Input
Full power will not restore. I was reteaching my nitrous management unit and something must have gone wrong with the APPSS2 wire. The problem resolved itself in the past, so im hoping for the same.
It could be anything from the APPS to its signal wires being short/open to the PCM, or the PCM its self.
Good luck! Lets us know how yours turns out. Ill do the same.
