Problem with cylinder 1 spark plug.. keeps going bad!

[jstevanus]

My first problem was a rough idle, got the cylinder 1 misfire code from Autozone, did my research here, and replaced the spark plug. The problem was solved. Then, less than a year later, I had the same problem, and solved it by replacing the plug again! Why does this keep happening? I've asked a few car guys I know, and they had no idea. Does anyone have a suggestion or three? Any help is greatly appreciated.

Edit: I found a post HERE where they are blaming the oil consumption issue. They say oil in the cylinder is destroying the plug. I've read that GM now has a solution for the oil consumption issue, but how much is the fix? I have no warranty.

You can get the dod tuned out

Not sure on the cost of the fix from GM.

But DoD is known to cause more oil eating than normal. GM says up to 1-2 quarts per ~3,000 miles is normal.

I would say the more miles on the car, the more its going to happen. But if you are only having the issue on 1 cylinder almost once a year, thats not really that bad IMO.

try some Z max or something like that, you never know it may work.

I'd yank out DoD and have it removed via a PCM tune.

Not only can you pedal a car to get better MPG's, but from what I've heard the factory files on the LS4 are awful.
