Well, following my cleaning MAF post, here are the coils. This is a great way to both clean, and repair any cracks on your coils. You need to do this! The performance difference in my car was night and day, and I thought it ran strong before. I'd like to thank Joe (SECUR1TY) from Skylineowners.com for pretty much all of this.
1. First take apart your coils (rubber boot and spring off)
2. Get a dremil drill set out and lightly sand back a very thin layer on the inside of where the little spring sits inside the coil, marked on the picture.
(around a teaspoon of build-up came off the inside of my coils). This was the gunk that was stopping the current getting to the spring, to transfer to the spark plug
3. Take your springs and bomb them down with electrical contact cleaner. Wipe them off, and then sand the carbon tip with a lite sand paper to get any build up off and to help clean the contact surface. Once the springs are all cleaned up, stretch them out a little before you put them back in.
4. Tape your coils up just for a little assurance. i used electric insulating tape up the top, on the front of the coil and down the stem
5. Spray some WD40 into the coil pack to stop it from coroding.
Done.
After I put it all back together and fired it up the revs seemed to be sitting a little higher (from around 700 previously to around 850-900 now). Took her for a spin and almost splattered in my pants from excitement. It redlined so bloody quick without hesitation or losing power (as it did previously).
Theoretically you can gap your spark plugs back to 1.1 to allow for a better spark because now there is nothing stopping the flow of electricity down to your spark plugs.
Another fix would be to use araldyte around the cracked part instead of the tape. If you do, make sure you do it in a this layering system (about 3-4 layers), but I recommend doing the dremil.
