P0175..(System to rich bank 2)..HELP! Ok I just got rid of my 85mm maf in exchange for a stocker..the car has tuning but for a stock maf not the 85mm..so i am driving back home from work and it trips the ses light..I get home and put it on my scanner..p0175 is what i got..could it be the maf telling it to throw in too much fuel at idle?..at WOT it pulls harder than with the 85mm maf on it..the car ran rich at idle with the 85mm though 2..could the 02 be going bad? why would it only say bank 2? Thank's any help would be awesome

Re: P0175..(System to rich bank 2)..HELP! swap the 02's around ....reset the code...and drive again... when it sets the code again.....if it changes to bank 1...then its the sensor. and you would pull harder cause puttin in the stock would richen up the mixture a little....car tries to get 14.6:1....but if its tuned for more air(85mm)(and our tuning usually shoots for the 0 or 14.6:1) then you would be running rich....Ideal for power(but worst for fuel economy) is 12.6:1(rich). If its too far past that..it would throw a code
