had 3 codes, 2 maf/afm ones, and a code 52 from knock sensor. cleared those out after i replaced the maf. wired the knock sensor to the brown wire off the harness that had broken off, and it cleared out the 52 code, but replaced it with a 51. im guessing my knock sensor wiring is still messed up so i think ill just do a rewire tomorrow with coax. if anyone has any ideas, please LET ME KNOW! I am about stumped...
