Hey guys,
Getting lots of misfiring on my R32 GTR. Car ran too rich and plugs fouled up (using NGK iridium, 8 range, gapped at .8mm). Anyways, got the car running, for about 15 min it was running on 4-5 cylinders, finally cleared up and is running on all 6. Around 6000-7000 (in neutral) i'm getting backfiring/misfire. Also, throughout the revrange, anytime I get into boost i'm getting these misfires. I can go partial throttle (maybe 35-40%) and get into boost to around 10psi, but thats it.
Also, sometimes it misfires then the ignition cuts out for a second (rpm's start falling even tho I have my foot on the gas), then if i let off and give gas again it starts to accelerate until I misfire again.
The plugs when I took them out where completely black (not wet though). Should I be getting a new set of plugs? The iridiums seem to be fouling up a lot, should I go for some platinum's? Possibly coils or the ignitor?
Any help would be greatly appreciated. Also, the car is running an Fcon V Pro (only 1 tuner within my coast, and they have no time right now to tune or look at it).
Thanks
