On my 1989 Bronco with the 5.8 I have been having problems with the MAP sensor. It went bad in February. Truck wouldn't idle or rev. Replaced with this one from AAP: http://shop.advanceautoparts.com/web/Par...chedFrom=header It fixed the problem and lasted a few months then went bad again. I replaced it with another one from AAP under warranty and that one failed again today. Pulling the codes confirms its once again the MAP sensor. I know BWD/Standard motor products has 2 different "lines" of products and this is the "T" which is the cheaper one. My question is could something else be killing the sensors or am I just getting bad ones?
