So i was driving the other day when the my GT just started sputtering and barely accelerated. I pulled over and looked under the hood to find a spark plug had worked its way out of the engine. I drove the car home and replaced all the plugs. After replacing them I took the car on a quick test drive. Everything seemed fine until i floored it and then a large BOOM sound came from the engine and the same plug blew out again. Has anyone ever heard of this? The 1st time it happened there was no damage to the plug at all, and the new spark plug tapped right in, no problems. The second time it happend there was some damage to the new spark plug; the threads were bent near the electrode and the electrode was bent all the way down. Any help would be greatly appreciated

This has happened before on StangNet. Everybody else took their car back to Ford, that I read about.

Do you have stock heads? The reason I ask is if you have FRPP heads they use a different plug that threads all the way down.

I remember someone posting a link to a product to fix this (sort of like a heli coil) but I didn't save the link. Maybe a thread bump will help.

helicoil kit will help you drill a brand new thread in place of the old one if that is the problem (ie the spark plug thread is screwed up)...

Not sure about the heads. But I'm willing to bet that removing those tail lights will DEFINATELY help you out.

So the plug does get tight? If it does get tight, I don't see how it could just come loose..

lights ...

Did it have something to do with your nitrous bottle prop rod?

"Assuming" you still have the stock Ford plugs in there, and you didn't actually have the nitrous hooked up, Ford "should" warranty it for you.

Same thing happened to me and they changed my head. It's a well known problem in the 2V heads.

Good luck.

Now when it happened to you did the threads strip out? Mine dont seem to be stripped, although I havent really had the chance to get a really good look at them. The plug threads in no problem without being loose, so i dont think they are stripped. Unfortunately my car is out of warranty, with aftermarket plugs and they game me trouble for my nitrous the last time I went to ford with a cracked intake manifold.

What kind of plugs? I have been told the Denso plugs get real hot and can pop out.
