Almost all spark plugs in this condition. Not sure if it is normal or not. The cars but on idle sounds like it wants to shut off but doesn’t.

    21k miles and already on its 2nd set of plugs and they look like that? (Unless gm is using ngk plugs instead of delcos now…)

    My car was misfiring last week I didn’t think it could be the plugs because they had about 7k miles on them. I did modify and tune my engine so I knew more maintenance would be involved. I bought the plugs anyways and bam misfiring was gone. They didn’t look like yours, in fact they looked in great condition but it fixed the issue.

      I put in oem plugs but someone else did recommend better ones. Might try that. Thanks for the info!
