Rough Idle and these codes...
P0174, P1151, P1443, and P0171....could all these codes be connected some how? Or caused be the same part not fuctioning right? Getting bad gas mileage and the egine pulsates sometimes....idle/ even when just driving around. I know P0174 and P0171 are banks 1&2 running lean. and P1151 is emissions control system(something like that). Any Gear Heads have any extra info to help me figure out what could be broke on the old 97. Need help please. I just installed all new O2 sensors too.
