Yes, 'suspect' coil produced a spark on the 'good' horizontal cylinder.(Thanks for advice on not to sandpaper terminals - too late! Ha! That's first thing I did! Why shouldn't you sandpaper them?) But only had spark on the one cylinder. I've done a continuity test from suspect coil wires back to connector box and they ok. Then wires go into PGM. Can I test through the PGM? Is there a wiring diagram any where?
I'm not a mechanic by any stretch of the imagination, just keen and frustrated amateur. I like things like seized bolts that I can hit with something! Ha! Anyone got one of those machines they have on Star Trek that you just wave over the offending item and all is fine and dandy?!
Most of the pins and pegs within terminals are coated in a super thin coating which improves conductivity and resists corrosion...sandpapering or using emery is the default reaction of everyone, we have all done it one time or another.
