Oooooffff. Rough looking spark plugs

[FullForceRam]

Wow.. we were getting ready to leave to Reno, NV from the San Jose Bay Area, Ca to take our daughter up to college last week and my truck stalled on me out of nowhere. Parked it started back up and it was idling rough with no codes.. weird. 08' Ram 5.7 with 262,000 miles and it was 60K miles from it's previous tuneup.

So I have it towed to my mechanic and he said he was pulling a Cylinder 7 - Misfire. Pulled the spark plugs and wouldn't you know it, there were fried! One of them even had a missing the center electrode! yikes...

Said he blew out the cylinder but whatever was in there must have blown out of the exhaust valve. Ended up replacing all spark plugs plus replaced the cylinder 7 coil pack just to be safe.

Strange that non of the other spark plugs were this bad though... Any thoughts on why only happened to those plugs? I know I have a lot of miles on her but I stay on top of all maintenance and repairs.

Wild Ass Guess: Bad spark plug in the cylinder or failing coil pack. Basically agree with what your mechanic did.

Mine's was the same way. I'm going to replace my spark plug wires with the high performance msd red for my 05 dodge ram 2500. Way better performance. Look it up.

I've seen those too, but at this point with over 262,000 miles on the engine, I'm done "upgrading" for more power. Reliability is now the game I play. Actually had a guy offer me $6500 just last week for my truck.. lol, it's not for sale.....yet.

Nice looking Rig the older ones do have allot of body lines, hang onto it and keep taking good care of it.

I would put a couple thousand miles on her and pull the plugs again to inspect.. I also suspect the coil, but a slight vacuum leak could also run the cylinder hot..
