1997 ford explorer xlt
I drive a 97 explorer with a v8 i have put a K&N cold air kit on it and modified my own exhaust with a cut out after the cats and a glass pack behind that. After i did these it has started to throw P0171 ans p0174 codes which i know are the lean codes. Anyone know of a fix for these codes my thought is my O2 sensors have gone bad.
