Spark plug question
 
1 Attachment(s)
Had a misfire on cylinder 1, pulled the spark plug and found this,
Never seen anything like this before,
Would that cause a misfire? Gap looks pretty close, but look how lopsided that top part is compare to the plug, surely it wasn't that way when I put in the plugs about a year or so.

Did the misfire go away after you replaced the Plug ?

So far, yes. It almost died at idle when It went into slow idle mode before, now engine Is running smoothly.
