Rb25Det Neo Problem

[Bronx]

hey all, lately been having 2 problems with my car, most annoying one is missfiring randomly, just random times it will missfire cruising or standstill, but to remove of the misfiring i just slam the foot to the floor and build up boost and it will go away..... any ideas??? just changed to new sparkies, and had the splitfires in for about 5000km.

this really really pisses me off. car sounds all nice and roaring and then all of a sudden its a god damn tractor!

2nd problem is, if i come around a corner or i do burnouts the car will smoke up to a certain point and them it just cuts out, never used to do that. i hit about 4krpm and then even with foot to the floor the engine will just cut off, completely and just go into idle mode. never die, or stall, but just stay at the 700-1500rpm even with foot to the floor.

i dont have a traction control in the car, and even on full tank it will do this, i first thought it was a fuel related problem not getting petrol when swinging into corners.

any help would be appreciated.

r & r?

standard ECU?

list your mods

[Bronx]

mods be 0, only exhaust n coil packs are uprated. Also to mention, i can do burnouts in a straight line, but not when i swing round corners..... Even no wheelspin, it still cuts off

found problem of miss firing, the coil pack loom had a couple of wires loose, was a touch and go miss firing.

still problem with engine cutout under hard cornering though, cant go track days

[SS8_Gohan]

sounds like it's entering R & R (rich and retard)

get a Nistune in it so you can get some control over it

where the splitfires new or second hand?

[Bronx]

splitfires were brand new, missfiring fixed, one joint on the plug loom was loose so didnt get a proper connection, fixed that and now seems fine *fingers crossed*, other problem still exists.

saving up for a Power FC after i get my FMIC and front plenum sorted out.

that top plenum is the biggest btch

problem will not be r&r, so ignore all posts about that. if it is only when cornering it is going to be an electrical issue where something is losing contact while cornering. i would hazzard a guess and say the afm. try checking the fault codes.

[Bronx]

how do you check fault codes??? i had it on a scanner once before, and it was all fine, guy said not a single problem.

[mad082]

do a search on here. i can't remember how to do it. i think you can bridge 2 wires on the diagnostics port, but i'm not sure with skylines. i just have a consult cable, lol.

well my car is a stagea well pretend its different then a skyline, but i shall search into this diagnostics thing, most things ive been finding is r33 and r32 stuff, will keep looking though
