i have a misfire kinda like bucking and hesitation plugs are new as well as coil and wires the MIL light is on with 2 codes one is for the down stream o2 sensor and the other is p0412 i know its something with the AIR system Im just wondering if this would cause the misfire. any input would be great BTW the o2 sensor was taken out after my turbo down pipe was installed and still had the same problem before i went turbo thats why i replaced wires, plugs, and coil. o2 sensor was new as well
