Machine Gun Sounding Problem

[Impact]

hey everyone.. so recently my r33 s2 gts-t has started to make some popping/banging type sounds when i boot it a bit (high revs)

it sort of sounds like a ak47 or something and i get no power until it stops.

in my old skyline years ago i had the same problem, and a spark plug change fixed it.. so i put a new set of plugs in this 33 but it hasnt fixed the problem..

just wondering what else could be causing this problem?

also the other day when i tried to quickly jump into traffic after waiting FOREVER (somewhat achieved a "peel out") the car hit limiter and instead of wheels spinning, the car made no power until i completely backed off ... any ideas?

thanks in advance.

Its misfiring. Your coil packs are fizzled. Wrap em up in tape. Also sounds like you hit rich and retard. Flat power til the limiter. Could be due to flooding the O2 sensor with fuel and the car is shitting it self.

The machine gun is the best way to explain the sound. Also sounds like the car doing a shit.

taping up the coils is a bandaid solution and doesn't fix the solution, just masks it. sometimes it doesn't do anything and the problem will remain. best thing to do is to get some new coils. this is probably also related to the other issue you had as well.

another temporary solution is to gap your plugs down to 0.8mm or if they're already there 0.65. i ran that for a few months before i bought new coil packs.
