I didn't mean to snub you by not responding to your info about changing plugs. I just did it last night and all went fine. Tips to anyone attempting this; remove the bottom radiator bolt first; then the one on the left (clutch side) and slide the rad toward you, it's on a "peg" or stud; only one bolt on top. Neat set up.
It's easier to remove ALL plug wires (they're numbered), gives you more room to work.
I did this with 12,000 miles on it and the plugs I took out looked good; golden brown. And yes, it did make a differnce in performance. Seemed smoother. Maybe it's in my head but...
Thanks for the info..
