I've never known fuel infection to hurt performin' ants of a motor before?
Something must have been amiss?
I was talking about the keyswitch tumbler that plagued Ford for several years in there.
Others (Toyota?) have had issues with their switches as well, but I think Ford had the worst trouble with them.
My step dad lost a nearly new truck one day.
And you could drive down the hwy and see a Ford truck burning on the shoulder, and you just knew what the cause was.
I think they have moved some of that circuitry off the tumbler and down to the black box under the hood and use relays now.
