sounds like we have our answer. That plug probably hasn't been changed since the day it rolled off the lot. If you got it yourself...congrats! That metal is most likely long gone!

 

Well if they did change it, doesn't look like they followed the TSB because it sure doesn't look like there is any anti seize on that plug. Unless you cleaned it up before the pic. Also, you might be running lean on that cylinder and it burned the plug up....I wonder if all is well with the injector.

 

They never used any at all, plugs were all clean. I got the truck running good again, I had a break in the wire on the coil plug at number 3 cyl but I got that all fixed up. But the truck still doesn't have any power when I get above 120km/h, I had it out the highway and it just seems like she loses all power at that point and I got bad audible spark knock, my truck is supercharged for those of you who don't know. I got a tune from ford racing and I'm gonna change the parameter tomorrow but I dont know, I think I'm gonna trade it in on a new dodge sport, I love the truck, but i'm sick of all the trouble... it's a money pit and i don't have a warranty because of the supercharger.

 

Spark knock, it's caused by a advance in timing or bad fuel? but I only use premium. When I come to a stop and step on this thing W.O.T, it has bad spark knock and doesn't really have any power, I'm afarid I'm gonna burn a hole in the piston or something. Can anybody chime in? I'm soon gonna have a bon fire in my driveway.
