Bending spark plugs!??

If been having misfire issues on my 06 lgt 100k

I checked everything that I thought it could be

And my mechanic found a bent spark plug that was shorting out causing the problem, changed the one bent spark plug thought we fixed the problem drove for two days then

Just cruising on the highway and started misfiring again took it straight back to the mechanic and said that it was a different spark plug that had bent that this time

 

Is my Engine fucked

ok good im not the only one ... mine come on with egine flight on and cruise flashing and i checked the sparks and wires and i needed new one then all of a sudden it stoped for a week then came back on keeps on going on and off misfire then no misfire >.<

Yep same thing here after I replaced the spark plugs it runs fine for a while then randomly dose it again

Would like to see a pic of the plug. Bone stock engine?

I have a k&n air filter

And I think the person before me had some sort of access port

Wrong plugs? How far the electrode extends into the combustion chamber is one of the specifications. I learned this when I changed the plug in my lawn mower.
