R33 Gtr Surging Issue

[R33GOD]

Hi guys driving my car before i felt a slight miss/surge and didnt worry about the problem.

Driving home on light/medium throttle car hesitates and surges and wont go anywhere even if i try to put the accelerator pedal flat to the floor while its happening. Dont think its spark plugs cause it dosent do it on high revs.

Advice please.

Thanx

only thing i can suggest is that my petrol was very low. near reserve, and was doing it then.

i put 30 litres of fuel in and it done it once again. Few minutes later everything seemed fine and is running back to normal.

Is this a fuel pump problem or maybe i just picked up some crap out of the bottom of the tank?

could be a poorly mounted pump

BOV's are stock i hope

guessing this would be a matter of elimination. plugs, coils, afm ect... run ecu diagnostic. do a search on it there is plenty of info

[R33GOD]

i did search thanks.

then i posted this topic.

yeah ash bovs are stock...

[R31Nismoid]

pump might not be mounted well, i'd start there

ok went for another drive now the problem is getting worse.

at idle the revs just dropped to 0. basically car nearly turned itself off then started straight away by itself.

Then had to nurse it home cause i couldnt go past 2,000 revs as it will just splutter and hesitate/surge.

AFM's

can i just clean them or better to replace?

if its not that il get a fuel pressure test incase its fuel related.

[jarrod83]

you can clean them with contact cleaner, theres also a diy thread around about how to resolder the point inside the afm incase they have dry solder or have gotten lose.. pretty simple and easy to eliminate

or you could buy a z32 one but once you start replacing parts it gets expensive =P

how low is the fuel tank atm?

[R33GOD]

about 1/4 of a tank

[R31Nismoid]

Well you said it was playing up regardless kinda?

I reckon its either AFM or pump mounting based on what you've said.

Try cleaning them, but i doubt it'll fix it... the insides where the elec stuff is will be the stuff thats causing problems = replace

[R33GOD]

gonna take it tomorow to get it checked out on the laptop.

tuner thinks maybe TPS problem.

[johnbarry88]

id say tps or afms its a fuel or electrical problem somewhere..

[STATUS]

fill tank, if problem goes you have pump mounting issue. if it persists i reckon it is afm's

[R33GOD]

went to my tuners today and error code 12 came up which is my afm's are screwed. Anyone have a good set i can buy at a good price?

nissan want 600 each. screw that

[heller44]

try repairing them first

[R33GOD]

who repairs amf's?

[Strik3r]

you do it yourself..

search SAU for AFM +solder

you will need a stanley knife, a soldering iron and some silicon if you want to put your afm back together properly.
