ok... working on my 2002 mazda mpv- 3.0 dohc.. pinpointed my main issue to the maf sensor is fried... all 4 auto parts stores in town had the part for my van.. or so i thought. the new part bolt holes do not match up to the maf sensor housing! approx. 1/2 an inch off... anyone else had this problem? did someone install the wrong housing on my van? i'm at a loss...
