My patience is gone I am ready to blow this piece of crap up.
In speed density everything is fine all the sensor readings look good, plug the MAF in and it goes crazy, O2's go lean at idle and stay there (between 0 and 40 mv) and the STFT's lock at 19.5% until I step on the gas the O2's go back to moving up and down like normal and the STFT's go down to around 0%. The car rocks back and forth at idle and smell like gas but throws the P0171 and 0174. In speed density none of this happens, I have changed the MAF, MAP, checked the fuel pressure and vaccuum and Headers seem to be leak free. The only other thing that it could possibly be is the PCM or bad wiring to the MAF but I have no clue how to check those.
I am at a complete loss with this piece of crap.
