read on vortex that this means i could have a bad maf.... i DO have a bad maf per other thread but if my cat is bad as well then i will constantly throw codes... is there a way to cheat the cat and trick the sensor? I live in minnesota so theres no emmissions testing or anything i found online somewhere a part that i can plug into the cat sensor to give it a certain voltage or something so it wont throw any codes. opinions?
