Miss Fire On High Boost

[Rock&Roll]

I have a R32 GTR and I started to get the miss fire problem that is commonly associated with coils earthing out on the head. The symptoms was a miss fire when boosting past 12psi. So I tossed up getting spitfires or yellow jackets. I'm a tightness, so went the yellow jacket route. A month ago i replaced the wiring loom that connects to the coils and the plugs.

I've got a couple of boost levels on my boost controller. Since putting the yellow jackets, I can ride comfortably at 15psi with no problems. When I turn up the wick, to 18-20psi range I start to get a small miss fire.

Even though the plugs are two months old, do you think this is now the problem? Could the plugs get fouled in 4 weeks of drive without boosting due to the old coil leak? Do GTR's chew up plugs?

thanks

Did you gap the plugs down?

Did you gap the plugs down?

Yeah, .6.

Fixed the problem.

I replaced my plugs and now the car doesn't miss a beat at any boost level.
