hey gang.

The title is most of it. I have a supercharged 05. Lately i've been seeing misfire codes in all four cyliners.

I think its my plugs so I'm in the process of changing them right now. I pulled one plug. (a colder aftermarket plug) and examined it.

It has alot of black soot around the ring. and greyish discoloration with a few deposits on the hook. no noticable damage to the hook.

Is this an indication of a rich or lean environment?

And has anyone else had misfires with their supercharged application? I can't seem to get this problem fixed and would appreciate help in diagnosis.

Thanks a bunch
