Well I know the coil packs don't like to get wet. Also if they are replacing them with the cheap ones (not actual ford parts) then these are really prone to failure (worse than the factory ones).

The factory plugs on the newer trucks are platinum by the way.

Good Luck,
Matt

You can get replacements on ebay, but they are not factory ford most of the time. They are a whole lot cheaper than the factory pieces, but you get a bad one from time to time from what I hear.

you really need to get the platts back in the truck. the coilsput
out to much voltage for the nonplatts and will erode at
a much higher rate causing out of plug gap misfire
what kind of gas system was put on

ok...i've looked on ebay and what i could find is only aftermarket coils which are cheap but is no point if there no good ,the gas system is called ZAVOLi ALISE , the engine check light is coming on aswell when is misfiring ,is there any way you can check the error codes without a computer and a program ?cos i've got a nissan 300zx tt and i can do a ecu check mysefl and see what errors is got

have them pull the code at autozone. If it is a particular cylinder's misfire code then I'll bet it is the coil or it could even be an injector.

I haven't heard anything great about the ones on ebay, but you can get 2 or 3 of them for the price of one of the real ford ones..... maybe worth a try.
