Right, i took the car out earlier and filled it up with fuel, after this its felt fine, no missfiring.

 

Ive just been out with my dad (so he can check it too) and it was fine on the drive revving it. We took it down the road and it was all good until i went round a corner and it started to missfire, then it ran smooth again.

 

It missfired abit more every now and then but not as much as in the past few days where it missfired all the time.

 

Could it be the fuel filter? If so where is it?

here ya go mate

Thanx again

Just a little snippet on this subject; Does the ZX have a filter in the fuel pump inlet? I ask this because I once had a Renault Five turbo which missed and popped and slowed. After much trouble and worrys of a failed turbo I discovered a small cone filter in the pump inlet pipe which was partially blocked with fuel tank debris, a quick blow through and all was well.

Theres French engineering for you.

This sounds like an intermittent electrical connection problem to me.

Ive just been out in it again and its perfect :confused: apart from when i go round one tight corner and it missfires. Im getting a new fuel filter tomorrow from nissan so i'll see if that changes it at all.

Dont forget to check the "nyon bag" filter on the fuel pump pick up.

That will block before the engine bay one does.

If its doing it when the fuel tank is low and going round corners then it has to be a fuel issue. Especialy as you checked all your coils and plugs. Still think the fuel pump may be on its way out when its hasn't got the weight of fuel on the intake?

 

Defo change both filters first tho.

Where abouts do i find this: "nyon bag" filter , how do i get to it and change it?

 

Just got the other filter today, im changing that now.
