I'm in need of some help with this one. A while back I started pulling some DTCs. A P071 bank 1 lean and P075 bank 2 rich at the same time. Then maybe a day later it would reverse with bank 1 rich and bank 2 lean. Now when I start it cold it hesitates and sputters like it is only running on a few cylinders untill I give it a little throttle and then it comes back to life and runs pretty much normal. If I don't give it any gas it will die. The exaust right at start up smells very rich, almost like its flooded. At first it was only only once in a while but, now it is at every cold start. Now in the last few days I started gettin a P2A01 and P2A04 HO2S performance Banks 1 & 2 sensor 2 with a genaric code 1400. What do you think is going on And what do I need to do to fix it? Thanks so much.
have the same problem?
