If my old memory is still up to par, Think it has something to do with the
impedance of the platinum plug vs. the coil over.
Speaking of plugs, I installed a fresh set of AutoLite 3923s {gapped at 40}
& cleaned the TB today. Mr. Butt Dyno says thanks! What a PIA its to change
the plugs in the 4.7L! But I still love the 4.7L!
