Blowing Coil Packs

[brandkm]

2 years ago I got the p0300, p0301, p0302..................

So I replace all of the plugs & coil packs and it has ran great until 2 weeks ago, Got a p0302, replaced coil 2 w/ one of my "good" takeoffs from 2 years ago.

Today, got codes on all of the other cylinders (but not #2).

I bought all OEM coils and plugs 2 years ago when I replaced. Is there something I should be looking for that would cause these failures after only 2 years? I find it hard to believe that all 6 coils would fail on their own after 2 years.

Any Ideas?

Do you wash your engine compartment? If so the moisture can cause corrosion and failures. Also I cant over emphasize the use of dielectric grease between the coil and plug. This prevents moisture corrosion between the spring contact and plug.
