car playing up need help asap

[4youu]

hey guys as of last friday, my car seems to be playing up
it runs fine for the first few minutes then after a while it sort of just struggles to rev and it sounds like its gurgling, and poping i got told it could be numerous things
iv then replaced the coil pack, o2 sensor checked all my fuel lines and there all on tight, replaced the air filter checked all the plugs and leads and its still persisting,
sometimes i cant even put any pressure on the accelerator as it just pops and gurgles and sometimes comes to a complete stall.

has anyone got any ideas as i would like to go away for xmas, and not having a car also is restricting me from working as i dont have a reliable vehicle.


cheers

G'day mate,

When was your fuel filter changed last? Any air leaks anywhere? Not sure if there is a bit where you can see any error codes..

[DevilDRake]

Could be your exhaust cat convertor blocking up.. Out of everything you've listed it's the only thing i could think of :S

Fuel filter also?

It sounds like something that gets hot stuffs it, so try the exhaust first possibly?

[mr.vandervloet]

do those engines have crank angle sensors? i noticed my skyline had one.. started alright when cold but when hot, it was a prick

iv had the car a month its got 155 thousand on it

i replaced:

plugs
leads
oil filter
pump
oil
flushed it replaced coolant
fuel pump
fuel filter
o2 sensor
coil pack

iv put a 80 litre tank with my standard tank fuel pump it was working fine but do you think it could have played it up ?
its just really starting to annoy me but my crank angle should be fine cause even when the car is hot it still starts first crank and has no problems ?

i might re check my leads and plugs but i have no idea, anyone know how to bridge the plug to get the error codes ?

i had the same sort of problem with my last car vn v6 when cold fine when warmed up misfiring changed leads and it fixed it. but u said u changed leads

You said you've changed the tank, so possibly a bit of rubbish on the pick-up?
Could be worth checking, it's happened to me a couple of times the motor starts and runs ok until it starts starving for fuel, and then the fun starts.

[4youu]

how do i go about checking the pick up ?
when it comes to fuel and that im kind of a nub i just paid a mate to do my tank haha
but i had the tank in for like 3-4 weeks before the problem occured

try tip some cold water on your CAS when its running like a pig

Change your IAC Idle air control
Your fuel filter isnt the wrong way?
