Sts turbo and Throwing codes please come in...
Ok im driving a 05 gto with an sts turbo have 2 step colder plugs in , 47lb injectors, no cats and has been tunned with hpt by my brother.
Lately usually when its in the afternoon il drive my car for a while (90-100 degree weather) my idle only when at a stop will drop below 500 rpm and the boost/vac gauge also will drop to 13-12 on the vac side which normally stays at 15. Then my feels lie it has a bigger cam from the idle... shortly after my chk engine light comes on. It did this the other day for the first time (the CEL came for the first time i meant) but the check engine light went off couple hours later.
The codes thrown are....
171-to lean
131-02 sensor
131-bank 1 to lean
133
300-multiple misfires...
420-catalyst something bank1 and 2
430-bank 2
anybody else have this problem??

Since you don't have cats, go to the engine diagnostics > DTCs and set P420 & P430 to 3 no error reported and remove the check mark from the SES enable box. The P0131, P0133 & P0171 codes are for a fueling problem on bank 1 (right side) The P0300 missfire is probably caused by the fueling problem. Vacuum leak? I think you have a stock cam?
