Hey my name is ivan an I have a 2007 mustang gt. My problem is my engine light keeps coming on for some reason. Got the engine light check, code reads p0171 an p0174. K first I change my fuel fitler and a oil change, then my o2 sensors but just two. The ones before the convertor, then the maf sensor, then I got my fuel injectors clean but light still on. I reset the battery for 20mins an it went off but came bac on. But I do hear like a loss of pressure sound when I turn the car off. An I dont kno how to check for vacuum leak please help
have the same problem?
