Well today became delayed until today.
A trick for removing the plug wires is to hold the boots with both hands and swirl it around counterclockwise while exerting a bit of pull upward. This releases the boot w/o having to use a plug wire plier.
I found my spark plugs to be fouled on #1 cylinder and#5, #6. The rest were kind of mediocre.
I replaced with new plugs and it idles lots better.
Basically one can't expect a perfect idle with thiscar, but it no longer misses.
That tool for visually testing the current pasing thru the wire works OK. It determined the #5 & #6 as intermitant current w/o having to pull anything.
Job done.
Now for replacing all the brake pads, refreshing brake fluid and replacing the valve cover gasket.
