I followed this guys advice. Used an electrical component cleaner and a couple screwdrivers, files, and wire brushes. It made my bad coil work again. You might give this a try before you buy coils in the future. Make sure the boots are good. If they are cracked or split you will get moisture in there and have problems. Shall we get on the topic of the dielectric grease again? LOL

Thanks guys, I drove it into work today and the tick was gone. Summers22 would you recommend changing the boot and spring on them just as a preventive maintenance type of thing or just if I start to get a misfire? I would like to keep this truck a minimum of 10 more years so making it last is my goal.

That's up to you. You can easily check them to make sure they are not cracked or split and see how they look. Waiting wont hurt it either as long as you fix it quickly when and if you do get a miss. You can fix just the one giving you problems or all so theyre all new. Being rubber there are many factors that play a part in them degrading. The most common and constant factor is the heat. Others are salt, water, electrical shorts, exhaust blow by, and ect. Some will go down hill faster than others. Basically IMO (which I know you didn't specifically ask for but Im sharing anyways) you can do them either way.

Change boots and springs when you change plugs .. like changing plug wires in the old days
