Bent electrode on Sparkplug!!!



As the title says......I was running the bird a little harder than usual the other night then WHAMMO...running on seven cylinders. I pulled headers and changed all just for good measure (this has happened before when I had severe detnation..bumped timing down and was fixed) tested it on the road and at WOT it started to detonate and bent it again...Same cyclinder by the way....As long as I drive it like I just bought it, it runs fine.....You guys think I could have jumped timing somehow????? All input on this matter is appreciated!!

Thanks

Later

Might just be that 1 cylinder running lean. Time to do an injector balance check.
