Good diagnosis.
Whip it off and replace it.

ok it wasnt the inlet manifold gasket, its not the Maf either, i eliminated that today. No logged codes... i'm abit lost. Next step maybe fuel regulator? Is there a way to test them or clean them?

try leads champ>i had the same prob in my old vs v6 ute(was a doddgy lead) more than likely it will be the shortest or the longest lead that goes 1st( it did in my case it was the smallest 1)

ok i have read that the fuel pump should flow 1.25 litres in 30 seconds, i'm not if that is while cranking or while running. Ours is flowing roughly 750ml in 30 seconds while cranking.

Can anyone confirm the flow rate?

If thats what it says it would be about right - with key on - though I wouldnt have thought it would cause a miss - pull each injecter connecter off & see if you can find which cylinder it is & check the plug or lead & do a compression test.

 

[JoshSvc]

The injectors are fine, they have been tested, cleaned and new o rings fitted

Tps? Iacv?

 

[JoshSvc]

iacv is working fine, throttle sensor is lubbed up and rotating fine with spring pressure
