This thing has eaten 4 sets of plugs within 6 months, what gives, I have MoCrafts in there now, and I'm guessing that it's the prob, misfiring real bad when slightly leaning on accelerator, but seems to steady up closer to wot...same as it did when I fried the E3s..

Give the Autolite 764's a try gapped at .054

Sounds like the plugs arent the problem, why do you think they are bad???? Are there any burn lines down the plug, you know the outside where the wire pushes on to. If you are getting burn lines than your wires are bad, replacing the plugs are only temp fix until the wire skips again ruining the plug, or you have a bad coil. Plugs are simple and give very little problem.

My wires are only a couple months old, I have not pulled any plugs yet, just noticed it started misfiring today, feels exactly like it did last time when I had bad plugs,
and our plug gap is .052 - .056

What kind of wires did you put on it? Sure they're in the right firing order too?

And what exactly do you mean by 'eating' plugs? Are you seeing visual damage on the plugs, or are you having a miss that you've fixed 4 times with new plugs?

I'm having a mis that I've fixed with new plugs...
However I didn't actually pop the hood and look this time, just figured it was the same thing again..i went to my shop today, all it was, was one of the wires came loose from the coil, the clips are broke on a couple of the
and I guess this one just decided to pop off, so I need to warranty out those 2 wires that have broken clips

I have Vision 10.2mm in blue

Fixed wires, still ran like crap, pulled plugs, all burned, checked their gap... (.043) DOH , CEL codes both O2 sensors rich...fuel fouled

Not for nuttin but I am 98% sure we checked the gap on them and had to open them all to like .053 or .054 cause they were at .045 or something like that.

Coulda just regapped them and cleaned the plugs.

Umm have you tried coil packs, when they start going it will miss like crazy.

Give the Autolite 764's a try gapped at .054

No, autolite is a generic brand...nu uh

it was the plugs, fuel fouled due to mis-gap

Autolite 764 coppers are one of the best plugs you can get for the Mark but what you get is your choice. Many of us are running 764's .054 is the correct gap.

Yup, never had a problem with Autolites. Cheap, too!

Only plugs I stay away from is Champion. Never had an issue with Autolites.

Badgers!

No, we are talking about spark plugs....... BTW, whos Sarah?

a pirate stole what from ye butt?

Think Geno and some others run the autolites gapped at .048. If your burning plugs you have another issue somewhere else. Those plugs are not going bad on their own. Unless you gapped all 4 sets at .045

Changing the plugs that many times is not a good thing either. Aluminum threads start to fatigue in the head. Raises the chances of a plug blow out.

That's why you do it with the motor cold

Don't matter if its warm, cold, or hot. Everyone changes plugs at different temps, all have had blow outs. It's aluminum. It will fail. Every vehicle I've done was hot when I changed them. I've only had one plug blow out in 17 years of owning vehicles.

It was a 32v 4.6

Point I was making is is you need to find out what is fouling your plugs and fix it so you don't keep pulling plugs in and out. Every time you torque them you raise the chance for a thread failure. The time sert kit is not that fun, it works, but not a good time.
