Camaro Revs by itself in 3rd. help? - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Okay, i got a interesting question for those with my mods or without them. When i am doing a normal, in traffic, acceleration at around 2k rpm in my manual... while the auto transmission is going to third gear and sometimes 2nd, i get a quick acceleration...almost like a quick rev but its the car that does it by itself. Its only happened since i got the ported throttle body so i am assuming its because of the porting that allows air to rush in there better?

Im not really worried about it... but am wondering if anyone else gets this?

I drive automatic all not sure what gear it is but my car has always done this to me. I have an LS.

yeah I know. I check it all the time with the code reader due to my permanent cel from lt headers but I find nothing ever. just the catalyst malfunction in bank 1 and 2 from no cats

Definitely because of the TB.

It affects the minimum airflow which should be tuned for.
