I just logged on to post my breakthrough. I've been chasing an ignition miss for several years. It could best be described as 'misfires under load'. Typical ignition problem....textbook plugs or wires. I've gotten some excellent info from this site...nothing fixed it. Also changed out numerous 'good' parts. New plugs would do the trick for several weeks. As stupid as it sounds.....dielectric silicone around plug and coil boots cured it. 180k on the odometer, and it's running like new.
It's so simple, yet I'd never seen it mentioned. For what it's worth.
