Codes...please...help.... So as most of you know, my car has been throwing a P0171 code meaning system bank lean saying its caused by the secondairy air injection.
Well today, the car started surging hard upon accellertation as if it had power and then didnt and then did. It was also backfireing like mad. I pulled codes and it now says P0170 instead of 10171 which is system back lean AND fuel trim.
so this is killing me, ive been dealing with this for over a year and no place ahs been able to fix it. PLEASE HELP |
