Thanks Jeff,

Actually I'm using "Bosch Super" plugs (not the platinum kind). Interestingly, this is what "AutoZone" has regarding fouling pugs on their web site....

"Cold fouling is caused by a rich air/fuel mixture or an ignition fault that causes the spark plug not to fire. If only one or two of the plugs show evidence of cold fouling, sticking valves are the likely cause. The plug can be used again, provided its electrodes are filed and the air gap is reset. Correct the cause of the problem before reinstalling or replacing the plugs.

NOTE
If cold fouling is present on a vehicle that operates a great deal of the time at idle and low speeds, plug life can be lengthened by using hotter spark plugs."

Right now the car is set to 10 degrees BTC on the timing indicator of the dampner.
