Thanks guys for the replies. I will try all of the above. The PCV valve has never been replaced before (178,000 miles later) and I did order it thru fordpartsonline, and it should be here tomarrow. Saturday I am having the PCV valve replaced, new spark plugs/wires, and also a new radiator. Wew. Another list to work on.
But we will try the thf, and other suggestions.
Thanks again!
