I replaced both #1 and 8 coil packs twice and now after this time doing it the engine light came on and now there saying it is reading lean mixture which he says maybe the fuel filter just replaced or the mass air flow unit 175.00 or the air filter which was just changed. Please help it has a code but can't remember what it was
