Thread: Could it be Fuel cut?

    Sounds like a dogy fuel filter or fuel pump to me. . Change your fuel filter first. . Might just be clogged with dirt and what not from servo's then if problem persists then try fuel pump. .

    Its only when u mash the go pedal and go throught the gears, if you start in a gear and floor it doesnt do it. its def boost cut! as soon as u shift into 3 or 4 at 6000rpm it hits straight away 4000rpm. hits for a second lose power, than back full boost at 4800-5000!!(well im sure its boost cut)

    I'm with DOC. Given normal service and normal fuel, I'd say Fuel Filter is unlikely in this case. It is true that a grunged up FF will give that sort of response if it is really dirty, failing to feed on high demand. But the distinction with this case is that with a blocked FF, all performance will tend to progressively get worse with time through the rpm range. It's more common with diesels due to more frequent filter loading with wax or bacteria.

    All i'm saying is pull it out and check. .. Was told the same thing by many Nissan guru's and after much debate pulled her out and more dirt then actual filter. Just think of all the crap on the bottom of a fuel station tank, i only ever use premium 98 and octane booster in my R.

    Yes it does do this, my R showed no signs of this until high fuel pressure was needed 5000-5500rpm was mainly where it would happen, the car would hesitate for a spilt second and then continue to rev out as normal. . .

    But hey this is a 1994 import from Japan made as a racecar not a aust. spec sports car so maybe MPS doesnt run the same sort of fuel pressure to even have this effect. . .
