Demon,
My car developed a stumble/mis-fire/hesitation as well. Pulled the original plugs at 85,000 miles...installed NGKs like the AGSF replacements (extend further). Car ran great. Did nothing else but replace NGKs with the AWSF-32PPs, and reset computer. Day 1...fine. Day 2...little miss/stumble. Day 3...lotsa stumble. When you 1st reset the computer, its run in a rich mode. But as the computer learns, it leans things out. That's when the stumble starts.
Its real...and when that's the only mod done...something's up.
BTW...there is no chance of "physical damage" Good god would have happened the instant you started the motor. Don't you think Ford would have been inundated with broken engines if that were the case?

That is the factory original for 96 and newer. It is a single plat with a fine wire center electrode. The ones I took out of my car at 60,000 miles still looked very good. Personally, I still prefer the double plat plug and have been using the Autolite APP764 or the Motorcraft AWSF32PP which is the replacement plug specified for the 1995.

Okay. List this "number of us"
I've never seen you post before and never heard others say the OEM plugs have done them wrong.
Also with "copper" plugs be prepared to replace them every couple of months due to the waste-fire style ignition system.
For the record Autolite makes Motorcraft plugs so one equals the other.
Go with either AWSF32PP or APP764 plugs.
Stay far away from any POS Bosch plug.
Okay, I'll go away, Mr DemonSVT. But before I leave, I just have this to say. I wanted to save someone the same hell I went through this past year. mcgainer and I and others have been complaining of this problem. The solution was to replace the Autolite or Motorcraft OEM plugs with something else. So, I'll shut up already about the plugs and let you guys struggle with this problem on your own. - Randall

I replaced my AWSF-32PP plugs last night (4 weeks old). They looked fine. Did not reset computer. The only thing I did was pull 6 plugs and replace with the NGK single plats. No more stumble...hesitation...miss. Car runs great again.
Explain that...

I will try to make a quick guess.
You say that ALL you did was to replace the 6 plugs.. okay.. agreed..
Have you ever changed your plug wires? if not, then they may have begun to errode, and will conduct poorly.. Unless you know of a way to remove the 6 plugs without moving the wires at all, then I would imagine that you moved the wires. Having done so could have re-seated a few strands to make the idle run more smoothly..
I had a hesitation, stumble, and replaced the plugs... The problem went away, but, just as you said, by day 3 is was back.. I thought it was my new plugs (just as you do) but, when OBSERVING things, I started looking at my wires.. replace with Ford 9mm wires.. and the problem will go away.. there is nothing wrong with the OEM style plugs...
Just a little note, to say that YES. its possible that something else is wrong, even if you *only* change the plugs...

Uhhmmmm..look at my mods..already have the 9mm wires...ran poorly with AWSF-32PPs and the 9mm Ford wires. Replaced with NGKs...running super.
I'm not trying to start a pissing match here...just stating the facts. My entire top end is new/clean just 2 weeks ago. If it runs poorly..and you replace a part..and now runs great...good money that that part was causing it...right? Maybe...as previously stated...a bad batch was produced? Build up resistance with heat over time? I don't know...I do know my car runs great again and is getting great mileage again.

Wow, I would never guess a simple question could be so contraversial. I put plugs and wires in about a month ago - Bosh Platinum +4 and Autolite wires. Someone at the CEG site recommended replacing the old stuff (123K miles on the car) to solve a momentary misfire problem and it seems to have done the trick. I don't expect to have to change plugs and wires for another 90-100K, so spending $4 for a plug instead of $2 didn't seem like an extravagance. Good luck with whatever you choose.

I strongly suggest you look at the two plugs side by side.They most definitely do stick into the cylinder an extra 5/8" This sits directly into the incoming air flow from the intake valves and leaving airflow to the exhaust valves. Major detractor for promoting good airflow and proper chamber swirl.
