P0171 (M) 1/1 Fuel System Lean A lean air/fuel mixture has been indicated by an abnormally rich correction factor
I noticed my MPG went down about 50 miles per tank.
Im guessing the o2 sensor is bad and needs to be replaced? Or is it somthing else?
I just installed a Full 3" Spin Tech Exhaust system with a Set of Mopar PPHs...
Mopar PPHs > Mopar Crossover/ypipe > high Flow Spin Tech Cat > Spin Tech Muffler > Side Exit Tips > all 3in..
anyone got any ideas on whats going on?
Im going to try to reset the PCM Tomorrow and then run it and see what happens, if it comes back im going to clean the bank 1 sensor, and reinstall and reset pcm, if that doesnt work i planned on buying a new o2 sensor..
or do i need to do somthing else?
