I have a Chevy Aveo LT 2009 and I’ve replaced the throttle body 4 TIMES! The first time it happened I was experience stalling, jerking, loss of acceleration, etc. eventually my check engine light came on and I went to the mechanic and got the code read and the code was P2135. The mechanic told me that it was the throttle body so I got it replaced and then a few months later my check engine light comes on again and had the same problems.
I took it to another mechanic and surely enough he told me the same thing so I replaced it along with the accelerator pedal. And then a few months later my engine light comes on again with the same problems. I went back to the mechanic who replaced it before which was in and he said that the part was defective and fortunately I had warranty on the part so he replaced it and that was in February 2021 and everything was good. Not even 2 months later and the check engine light is on. I went to a different mechanic on 04/22/2020 and he read the codes and it was the same P2135. he said that it was the accelerator pedal and or the throttle body so I get the pedal replaced again and literally the next day my check engine light is on. Ive had 4 different throttle bodies and accelerator pedals in a span of a year, I don’t think that’s normal. I’ve spent so much money and I don’t think I can afford to get the throttle body replaced again! I intend on going back to the mechanic, but if anyone has had the same problem or knows anything please help!

im thinking you may have a wire connector problem or a wire harness problem.

70 L camino, grampa engine, g-force 5 spd, road rage suspension. Pray first before all else fails.

Yes, check the wiring. It's very doubtful at this point it's defective parts.

I keep coming back to a ground missing and the unit is now a poor ground.

Could be, the parts swapping mechanic is probably incapable of finding it.
