i just changed my maf sensor. i started the car up and then it stalled. then i installed the old maf sensor and i got the same result. so i un-plugged it and the car runs? but imeditley throws a code 34 (maf) then it stalls after about 1 min. so i unplugged the ecm plug to see if ecm would repeat itself and it does the same thing? im totally stumped please help me out?
