So I pulled the plugs because the car was still misfiring after a couple days of driving it. I found the #4 spark plug had a chunk of the porcelain missing. This was an old plug I threw in there a few months ago after breaking the porcelain on the previous spark plug.
Two plugs, both with broken porcelain, both #4 cylinder. Any ideas? Im thinking it may be carb related, maybe a lean run situation that is making the plug extra hot, but I am pretty much clueless right now.
