Hello everyone, I have a 2005 mustang GT with a lit check engine light; Codes are P0171 and P0174, bolt on mods are .62 mm BBK throttle body, cold air intake, kooks long tube headers with catted X pipe and SCT Xcaliber tune. I have to get this car through inspected so i set tune back to factory setting but i still have the lean codes. I was told that the cold air intake and throttle body may be causing the codes. Has anyone experienced this issue before?
