I am an 87 mustang converted over to mass air with a 70mm throttle body. From everything I have read from other posts the code on the mass air sensor should start with F2VF. Looking at mine it is F07F-12B579-A2B. From what I found through google one of the applications for this mass air code number is for a 5.0L Ford truck. The car runs pretty good right now, just a slight backfire in the exhaust when it is cold. Can I expect any type of change by changing over to a 'F2VF' mass air sensor? What would be the benifit of changing or what potential problems could be caused by leaving this mass air sensor in?
Thanks.
