    Sounds more like a bad cop or a vacuum leak.
    Yes officer... I am aware of how fast I was going!

    Stock COP's are the best thing for your truck until you start pressing beyond 450HP.

    aftermarket coils don't seal well against keeping water off the plugs, go with stock.

    Unplug one COP at a time. If you don't notice any change in idle you found your bad COP, and only have to buy one if you can't swing an entire new set of OEM's.

    I have recently switched back to stock cops. Tired of the moisture issues with Weapon X.

    guys have tried them out, and the general consensus is junk. Some haven't had issues with them, but many had, and they'll creep up when you least want them to I'd cancel the order now if you can. For $339 you could probably get a full set of OEM coil packs, or for not very much more get OEM's and KNOW you have good quality to last another 7-10 years.

    I beleive it IS NOT water penetration rather some sort of condensation.

    still not too late to return them for OEM's! The msd look purdy in the box, but their quality is hit and miss! OEM is a SURE thing!
