Re: Wierd F150 problem
86 was "bank fired" rather than SEFI....here is where a LOT of assumption
comes in to play... especially since this same scene wasn't tried with the
injector on a different cylinder. I imagine a number of contributing factors
including corroded connections and possibly a shorted injector coil... no
way of telling without testing but I can assure you that auto repair is NOT
as simple as most people think.
This could open the door for many other subjects, points of view,
experiences ad infinitum but I wont go there. Sounds like you got rid of a
truck that runs for the price of a truck that don't...
Knowledge is our friend.... this ain't rocket science but it does take a
logical approach to diagnosis.... electrical problems are much easier to
diagnose than we allow ourselves to believe......
