Any idea's???? I have a 02 f150 5.4 4x4
runs really rough 99% of the time. might get 10mpg and 5mpg pulling trailer
wont hardly make it up some hills without kicking down all the way
running lean on both banks
and now doesnt seem to be kicking down wright all the time
i have replaced alot, fuel pump, fuel filter,coils,plugs,EGR valve,TPS sensor, mass air flow sensor and most vacuum lines
i had them hook up the PC to it and they said one of the O2 wasnt reading anything so i replaced that one.
it also showed it was running lean on both sides, i was told that if it was the converters it would be running rich.
Iam willing to try anything at this point
