Thanksfor your reply. Yes, I have new plugs and wires (NGK's) and will probably be installing those Monday. I only removed the one closest to the big square plastic intake contraption because it was easy. I don't look forward to pulling everything out on both sides of the engine, but so be it. That's why I got the best replacements- so I won't have to deal with it again for a while.
What is this "terraclean" thing? Some kind of engine interior varnish remover?
