Seems like not a lot of people frequent the tech forums, so I'm linking my post for you guys... in short, please figure out why my #7 plug keeps fouling out...

Update on this... Today I replaced the #7 plug and wire. No change, still not firing... I need to just take it to the shop and have one of the more experienced guys diagnose it... but it's more fun to try things out myself...

have you done a compression test on that cylinder?, what does the plug look like from that cylinder?

 

[PhoenixZorn]

actually, when I pulled it last night, it looked dry... like a piece of shiny plastic that has been sitting in the sun for a few weeks... lost it's luster... almost looked like calification on the electrode....

Is it not firing, (IE no spark at the plug when tested) or as mentioned, do you have compression/valve issues?

i would check the compression on that cylinder, if it is a good reading take off the valve cover and run the engine to see if the valves are opening all the way
