Plugs are new, with the correct gap. No visible problems with the wires, but I don't have my volt ohm meter handy. Couldn't be the stainless steel connectors I used to replace the rusty spring connectors, either, the problem started first, which is what led me to start replacing them... its just weird. Maybe other coils would blow too, if given the chance, but I back off the throttle as soon as it happens. There's supposed to be a good auto electrical place in Louisville, but lost the address. I'll probably seek them out as soon as I'm done with the suspension...
