on my truck, the #4 and #6 plugs shattered, and the dealer had to rebuild the two cylinders, it put holes in the pistons. they claim that #6 cylinder predetonates and this has happened several times before. on mine, it threw a misfire CEL code. i posted on it a few weeks back. it was covered under warranty.

I have a later model hemi in my 03 now (under warranty).
Word of caution: Avondale Dodge here in AZ told me that nothing was wrong with the truck and sent me on my way after saying that i had not gapped my plugs correctly. I then went straight to Lou Grubb Dodge (barely made it there on the trucks last legs) where they put a scope into the cylinder and found the problem in a matter of minutes.
There is a huge difference in dealers...be sure they don't jerk you around.

Yes they are touching the electrode completely pinch shut and both plugs in the 6th cylinder one plug in the 1st cylinder and one in the 4th cylinder , the spark plugs were replaced at the dealership so I assume they are the right plugs used if helps will post brand and number tommorow after work

yes, pre-detonation is what i was told causes this. just between you and I, I had run 87 for a few months in the summer during high fuel prices. not anymore, its 89 or I dont drive it. mine was still fixed under warranty though. If you ask me, only fixing one or two cylinders seems like a bandaid though, but I couldnt talk em into a new engine. i tried lol.

89 or better is all i ever run...EVER.
I had one of the first Hemi's out in 03 and from what i'm hearing, part of the problem was design. From what i understand the later Hemi's are improved in this area.
Anyone agree or disagree?

Your engine is blown from running lean. If you are using a handheld tuner, then that made you leaner and boom. Chrysler engines do not adjust from increased air flow like Ford and Chev do. SD vs MAF
