p0036, p0030, p0135, p0443. These are the codes I got. When i clear them they come back almost immediately. The CEL won't go on, it will if I do 2+ starts without clearing the codes. My car started to cut power, but it went away, still got the codes though. Engine is running fine, no misfires/knock.
My car: 2005 grand prix gxp 150* nitrous, Catless DP, TEP trans, Custom tuning through DiablewTune.
I installed different maps, still the same codes. I did some research on the codes but could not find anything productive
