On a recent thread I started I posted some pics of my spark plugs, the pics looked great until 3 hours later and now only 1 out of the 3 are viewable so I'll post them again with my original question! A month or so ago my 454 was running rough so I pulled the plugs, cylinder #4 was dirty (pic #1) so I cleaned it and she ran fine. Last week it started running rough again so I pulled the same plug and it was ten times worse (pic #2) but after I cleaned it again shes running better than ever! What the heck causes spark plugs to foul like this?
PIC #1
PIC #2
Any idea's on what my problem is?
