I posted this in FTE forums and no responses.... So hopefully someone here would help I have the 3.0 flex just to clarify. But the other day I did the maf mod to it and now have a C.E.L. indicator on. The codes I pulled are PO171,PO174. So that means that banks 1,2 are running lean..... I unhooked the negative cable for an hour then let truck idle for 20 mins, it runs fine but after I drive for ten minutes or so that blasted light comes back on
, and Ive done this several times. What gives the only time I pulled a PO102 code was when I unhooked the M.A.F ... And heck I think it ran better than with it on "no pings". Whats making my truck run lean? If its the M.A.F is there any thing else I can do to it to fix this crap...
Oh and by the way its the maf that is complete cast alum.
