I have an 05’ GTO with a few mods, including cold air, headers, short shifter, etc but nothing crazy impacting.

As of recent, I had a P2135 engine code, so I took out my throttle body and cleaned it, threw it back in, deleted the code and the car was good. I’ve checked all wires leading to the throttle body as well as the wires connected to my gas pedal and nothing looks corroded or ripped.

However, maybe 3 weeks after I cleared the code initially, I ran into the P2135 again, so I parked my car and turned it off. To turn it on a day later and the code is gone. I’m not sure why it would come and go, or if this is just a sign that my throttle body or pedal sensor is failing. Please let me know your thoughts.
