Hello
I turned on my CTS 2003 at morning I found the light TC turned on. I tried to move the selector it was blocked on P. I just turned the ignition and selected Neutral and turned on the car it worked. I connected the scaner, it gave the stop lamps are broken. I changed the stop lamps and cleared the memory, the car worked normally for two hours and turned off alone. I turned it on, the accelerator pedal didn't work. I turned off and turned on the car it worked badly for 10 minutes and stopped completly. I waited 2 hours and turned on the car it works normally. Could any-one explain me what happen?

P0058: Heated O2 sensor circuit high, bank 2 sensor 2.
P0161: Heated O2 sensor performance, Bank2
P0638: Throttle actuator control range/performance.
P2101: Minimum throttle position not detected.
P2176Minimum throttle position not detected.

Sounds like your throttle position sensor and second O2 sensor on bank 2 have gone bad.

I can see vacuum leak if the only code)s_ pertained to the O2 sensor, but the 3 TPS fault codes don't lead me to think vacuum leak, since it's electronic as is the throttle itself, I believe.
