![]() I just took my v6 to emissions and I failed. The print out they gave me reported a diagnostic trouble code: P0171 And I checked my manual on that code and it said: "System too lean (Bank1)". I had just recently installed a MAC cold air intake, is that affecting the car; if so, how can it be fixed/adjusted?
Also, on mil status it reported "mil command on: fail" what does this mean? And last how do i run a test to find out why my check engine light is activated? Thanks |

![]() i aint no pro about all this or anything but i know that ford puts catalytic converters on the cars to control the emissions now if that has gone bad u might have to replace it or if u bought it used the other guy could have changed the exhaust and they messed with the catalyctic converter that could cause u to fail your emissions but this is just my opinion i dunno for sure though
