Throttle Body Help
I have been getting the P2135 code, and occasionally PO121, and my Camaro has been going into reduced engine power mode. When I tried to figure out what it was no one had a straight answer of what could fix it so I decided to start with replacing the throttle body. Throttle body works fine but when I go to shift it still revs up as if I am still pushing the accelerator. Also when I come to a stop in neutral the car wants to rev up to 2 rpm until I am at a complete stop, if I stay in gear and stop it wants to go to 1 rmp. Any ideas on how to fix this? I tried doing a relearn without a scan tool, I will try today with it though to see if that helps, but my next step would be to replace the accelerator position sensor and see if that helps. Any ideas would be appreciated, thanks!

Its the throttle position sensor on the pedal (70 dollar part) that is going bad (at least it was for me). Replaced the pedal, and havn't seen the issue since.

Not just chevys , dodge trucks it's very common for the pedal sensor to fail and get a limp mode too

Do you have a throttle controller? Vitesse or similar?
