If you've been following some other thread of mine, you'll know i've got a misfire , its the middle plug on the drivers side. i've whipped the plug out and the piccy is below, is there anything i can gather from the state of the plug which might lead me to the reason for the misfire.

 

Also the other piccy shows a pipe was disconnected i've no idea what this does so any tell me what would happen if it not connected.

 

Thanks

Fuel dampener is 2nd pic.

 

First the gap looks a bit large???

That spark plug looks worn. Try a new TT plug gapped to 0.035", Reconnect the fuel dampener vacuum line as you have

a vacuum/boost leak.
