If fouling still occurring, it is NOT electrical ( unless for some strange reason the PCM has a burned out transistor for that coil pack ).
Compression test time .....
180's probably right - broken ring.
Guys i have done everything except yank the head off. I have just been dumping new plugs in as need be on that cylinder. Haven't found a fix yet to make a post with. As soon as this winter comes around I will be pulling the head. Every thing is adding up to be a bad valve guide or seal. When I pull the head it will tell the story.
