RE: engine problem

Thanks for the feedback! It sounds like you have a good handle on your situation, just need to find the time and $$$ to fix it.

I have an F-O-R-D (I don't speak Its name) with 4.6L V8 which has blown 4 out of the 8 original ignition coils now, #5 through #8, so I'm no stranger to misfires. (It has coil-on-plug design, so no distributor or secondary wiring.)

The worst was when two, #6 and #8, went simultaneously on I-80 in Pennsylvania during a road trip under high acceleration while passing a semi. I managed to go about another 50 miles, but finally had to pull over and limp in the breakdown lane to the nearest exit in a somewhat civilized place (Hazleton), and call AAA for tow from there. The computer was a mess from all the false signals (including engine overheat) that it was getting from the two failed coils arcing over into primary wiring sense lines, and just kept giving up and going into shutdown (stall).

Being an engineer who has dealt extensively with cabling and noise issues, I was not impressed by Ford's engineering at that point.


Good thing--we don't haz so many old people (read, "defensive drivers") up here.

Mine is a 350 LT1 Chevy Smallblock, 5.7L V8. Mine has only one coil.

I couldn't hear the backfires, but even electronic timing can be altered. My experience with V8 engines is somewhat limited
