Codes P0171-P0174
Codes -P0171,P0174 Lean bank 1&2. I have a 06 F150 with the 5.4L. I have the Volant CAI and FlowMaster 70 series muffler and getting those codes. Will the EDGE EVO in the Tow mode correct the problem? I had the Volant CAI without the 70 series muffler and no codes then added flowmaster 70muffler and codes were popping up P0171,P0174. Is this a common problem?
