And/or overheated, this happens after engine reaches operating temp. The car started running rough and stalling the other day. When i checked the plug in cylinder one had a "smashed" electrode. I corrected this problem then the next day it happened again, this time it was the number 1 plug. Ive replaced plugs hoping to correct this problem with the same results in the no. 1 cylinder.

A valve seat could be falling apart causing the damage to the plug. Possible the belt jumped, loose wrist pin and worn connecting rod bearings for no.1
