Okay, that's a good thing to find. Do you need another SP connector?

Pressure sensor hose disconnected?

A good thing to do. Did it smell better then?

Traditional fouled plugs involved lead compounds condensing on the SP 
insulator. With lead free gas, that doesn't happen anymore, but it's still 
possible for carbon to get on there.

I don't suspect the ignition points, but when was the last time I looked at your 
distributor? If that was WAY back when, I may not have reset the trigger 
points (Do you remember?) I only figured out how to do this maybe 3-5 years 
ago.

Or, I hate to suggest this, maybe we've found yet another bad brain....
