Looking for some help on my Maggie'd L99 - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Long story short, there is something funky going on and nobody seems to know what it is or how to fix it. The car is an '11 and I'm running into an issue of random erratic idle and sometimes, if I shift from reverse and go to Neutral, it will die.

Also, I will randomly be sitting at a light and I feel a very faint bump (Like someone bumped me from behind but obviously did not) and the idle changes. It almost feels like the trans does something funky. Also, in Sport mode and paddle shifting, the shifts feel a little odd. The tuner also did the trans tune.

The blower was installed and the car was tuned at the time by a GREAT tuner near me. He really knows his shit. I took it back to him to go catless, install a Bo White ported TB and a quick retune. He said he drove the car home and to work the next day, did the work and drove the car home again and he said there absolutely nothing wrong with it.

The only codes I am getting right now are O2 codes if I really dig into the throttle a little. Codes 1133 and 1153.

I DO have a slight exhaust leak as one of the clamps loosened up a little. Other than these quirks, the car runs great.

Recently I installed new plugs and air filter but this had no effect.

Okay. I know about the codes. I'd rather not have the O2 sensors turned off in my tune. You know, they are kind of important.

If you are running catless, you aren't worrying about emissions. Just setting those two specific codes to no error reported still allows the front O2 to function, it just doesn't set the code for the insufficent switching. It will still let you know if you have a low voltage, high voltage, no activity, or heater circuit problem, along with system too lean or rich. It will still control fueling accurately when the tune is right.
