well i didnt get any replies about my spark plug question so i will ask again. i will be soon in the process of changing plugs, is there a better plug to run? should i just go with stock? thanks for the replies...i hope

 

Unless you have some major power adders I would just install stock motorcraft plugs at stock gap. Ford says there good for 100,000 miles, so the second set should get you as much again.

 

well my truck only has 44,000 and i have a miss when it rains, so i figured that i might have a damp coil pack? so i figured as i'm checking coils that i would change plugs.thanks for the input man!!

 

You probably have a bad boot on one of the coils, the hard part is finding the bad one when it hasen't set a code. usualy ther is a small hole purnt in the boot again hard to find, the boots are a few dollars from ford plugs are probly ok you just have to find the bad coil, when reinstalling remember to put dieletric lube on the boots.

 

so do you think that is whats causin the problem? the hole or the hole plus moisture? so do you think that puttin plugs in is a wasete of time? i also have a body lift on this truck, do you think that the water is gettin in from the cap inside the wheel well? should i put some gap guards on? thanks again

 

The dampness is probly causing the problem with the bad boot. I doubt that the body lift is causing the problem. Where the plugs are located the only way they canget wet would be from cleaning the engine. My 2001 F150 had a bad coil or boot around that milage it was the second one back on the passenger side, The dealer replaced the coil for me and gave me the old part when I looked closely you could see the hole in the boot. This was always a problem with these engines even when they used plug wires the boots get so hot in the holes that they deteriate. After the one was replaced in my truck I haven't had another failure in the past 2 years. If you have acess to a code scanner you can check for codes there may be one set eventhough there is no light
Ford dealers have a tester they can install and roadtest it if you can duplicate the problem.

 

thanks!! so whats your opion on checkin the coils? or boots? the boot is in between the coil and the plug right? are they a pain to check out? the fuel rail looks pretty close to the tops of the coils to me. looks like it could be tough or time consuming. but thats just me...

 

The coils aren't as bad to remove as they look. Get the right size socket I believe 8mm put a little stickum of some kind calking or something inside the socket so you dont loose the bolt, remove them one at a time bend the boots back and forth and look for a split. make shure you put dieletric grease in the boots or you will have a miss for shure. good luck!!!

 

thanks dude!!

 

It's a 7mm bolt holding down the COP's. when you take the COP off blow out the hole with air to remove the dirt in there.

 

will do. so far im looking for cracks, moisture or rust in coils and blowing out with air. sounds like an all day'er. ohwell i don't mind. like doing this stuff. better learn this coil on plug b.s because i have a mustang with the same set-up. thanks for the info.
