- 2003 mazda protege5
2003 mp5 5 speed. 2.0 all stock. it starts up then dies. unless i give it gas to keep it above 1k rpms. the codes that it throws is po102 po103 i also have a 2002 mp5 so i switched my MAF out of my great running 2002 into the 2003. and it still throws the same codes. I can unplug the MAF on the 2003 it doesnt fix the idle and believe it or not it will still rev and not stall out with the MAF unplugged. anything out there cus a MAF code to throw with a good MAF or why my car dont stall out with the MAF unplugged? runs great going down the road. im at a loss. only thing i can think of is broken wire. but i get 12v going through the power wire and the other 2 wires seem to be grounded good. so maybe bad ECU? i dont even know if i posted this in the right spot hehe sorry
