[s-cars] Coil acting weird?

[djdawson2 at aol.com]

 Another suspect component are the boots going from the coil to the spark plugs.? They get old and arc as well.? Last I checked, they were about $7 each... $35 well spent.

Good luck,
Dave

The wires to the coils suffer aging insulation cracking where they  
exit the cover, at the back of the valve cover. I bet there's some  
shorting going on, that you're fixing on the coils you're replacing.

A cheap, quick check would be to pull the coil cover, remove the  
little plate holding the coil wires in place, and, after examining for  
obvious bare wires, temporarily wrap each wire with a short piece of  
electrical tape. If your miss diminishes, chances are you're on the  
right track.
