I threw the 0174 code which is bank 2 running to lean. I got plenty of advice telling me to clean the MAF sensor or replace the o2 sensors. Which do you recommed and if so, is the precat or post cat. How long does it take to replace the o2 sensor or how much would a shop charge


Say I do clean the MAF...do I just take the whole thing out and spray it down with the stuff from autozone? Is there a DIY?
