This is a spin off thread from the code thread I posted. I drove my truck really hard and threw the code for misfire. I pulled the #3 plug and below is a pic of it with a new one. I have since pulled all the other plugs and they look OK. I'm trying to figure out what could have caused this. It looks like I just lost the gap from some reason. I know I have been running rich. I have kept it rich to try and prevent any damage from the STS turbo. I was planning on getting it leaned out next month with the addition of the VEC3 and some meth. So take a look and tell me what you think could have happened. I had about 17K miles on those plugs. I was wondering if this could have happened because I drove very hard and then just shut it off. I didn't let it cool down or anything. Well give me your input. Oh yeah it almost sounds like I can hear a tapping noise. My neighbor says it is the valve. It taps a few times right after start but then goes away. The truck is not smoking at all.
