Sounds like it misfiring - my r33 did it when i first got it, happens to heaps of skylines.

check around the forums theres heaps of articles on changing coil packs and plugs etc...

is the boost at stock levels or have you increased it?

does this sound like fuel cut to anyone?

[Ronin 09]

fuel cut would happen regardless of fullness of the tank. I'm tipping plugs.

[^DRIFTIN skyliner^]

oh well its running at 10 psi so nah its not standard...and it only happens when i have like quarter of a tank left but lately it was gettin worse an happening on half a tank... but its in the shop now so hopefully its gettin fixed... ill let ya all know what it was when i get it back ok cheers

[^DRIFTIN skyliner^]

well i found out my tank is full of shit it is rusted inside... an the feul filter was stuffed cause of it.. an they reakon i should get a new tank some how... cant ya jus clean it out thou?>?>?

[rbs13]

doubt it if its rusted?

[Cubes]

Have a look at it yourself and see if it is really rusted.

Unless you really trust the blokes and they arn't scraping for money just to keep their business going don't trust em'.

rusted fuel tank?

sounds like crap, unless it was left for a long time with no fuel in it?

yeah check it yourself, 5 min job to take the fuel tank cover off...

a new fuel filter is a good idea regardless....

[wrxhoon]

it would rust if it had water in it for a long time and very little fuel but would have to be siting there for a long time . have a look if rusted badly replace if only a little clean it up ,change the fuel filter , clean the pick up and keep an eye on ur fuel filter in the future rubish in it .

[^DRIFTIN skyliner^]

sorry to sound stupid but how might i take the feul cover off?>?

[Dr_Drift]

it's in the boot on the right hand side under a plate with 4 screws you'll find another plate with two hoses and 8 smaller screws, be carefull with the hoses etc...

[Blu32]

im pretty sure i have the same problem as u... how did u end up goin with it ?

Also where is the fuel filter ?

I have taken the plate off at the back and the 8 screws... is it ok to take the hoses off too ?

I can sorta of see the tank and the fuel does look a rusty brown colour... Is that normal ?

Thanks for the info...

[CGB_R32]

umm this could also happen from shit in the AFM therefore the ECU dumpin more / less fuel to mix with petrol that might / mightnot be there? or maybe a shagged thermo..? just suggestions.

ummm, is it stating the obvious that your car may be running an aftermarket fuel pump that wasnt installed properly, and what you are getting is fuel surge, i bet it happens going thru roundabouts too.

If its the std fuel pump check that its installed correctly in the std bracket. Coudl be a problem with the pickup

In an R32 GTST with std ECU, does the fuel pump run at a constant speed/pressure, or does it ramp up based on rpm and load via a signal from an ECU...i ask because i know of an R33 that with a Power Fc had the fuel pump whining at idle, but when the std ecu was in itm at idle the fuel pump was quiet and it was only when under load that the fuel pump whined...so assuemed that based on load the voltage to the pump was increased
