I have a question. Replaced all of my coils and plugs. Vehicle has been running good. But about 3 different times since replacing plugs..usually after lots of driving the truck starts missing again. Usually when Sitting and Idleing. If when I put dialectic grease on the COP and I got alot of Dielectric Grease on the actually coil spring would that cause a missfire. Read where you were supose to put it on Book but clean it off the metal Coil. just question. Think it that or I'm gettin bad gas probably. Did it today just after I Filled up with gas. But then Ran good for about 75 miles not miss.

Thanks

is it throwing a light for a misfire? try swapping coil packs from one cylinder to another. if the code changes from say cyl 3 miss to cyl5 miss its a bad coil. and it wouldnt be the first time a replacement coil was junk

Dielectric grease on coil connectors will not cause any problems. I'd do what pissedoff92 suggested.

Ok I pulled the COP and the Spark Plugs on 2 of the coils that I installed last. The first 6 were done by machanic. The ones I nstalled. I had gotten Dielectric Grease all over the coils. I read on this forum on a post on how to change coils that to take the boot off the coild apply dielectric grease. to the boot and after putting the boot back on the coil to take pipe cleaner and clean the grease off the coil. So I did that and wiped the grease off spark plug. Reinstalled the coils. And praise God the truck is running perfect. Drove 400 miles with no problem yesterday.

The grease really shouldnt have caused a problem.
