hey guys.. i used to have a misfire problem with my car r32 skyline gts (non turbo) about 4 months ago. but i fixed it and now it feels like it is misfiring at higher revs again (full throttle).. but i dont think it is misfiring.. i think it has something to do with fuel shortage. it has happened about 1 or 2 months ago and i changed the fuel filter and it went away but now its back ..... :S
wen its at high revs and at 90% or full throttle.. it makes a put put put sound...
low throttle runs fine and this problem occurs on some days usually the days when i run it hard... :S:S:S::S::S
any help is much appreciated!
