Can anyone tell me the correct fuel pressure for a VY V6?

is it an actual wideband AFR gauge ? if its just the commanded AFR then it looks like a lean cruise becomes active, if u have the ability to disable lean cruise then do that and test again to see hoe it goes (would have thought that TPS would be too high for lean cruise active anyway)

Vacuum leak?

Is that AFR based off the narrow band sensor?

I would say its just the commanded AFR and yes it's a bit late for lean cruise and it's up hill with a bit of a load, don't think this program does anything like that..

So how do you know the knock sensors are retarding the timing?

If the engine is under load the timing will be lower than when just cruising.

I would say it's based off the narrow band sensor, I did have the dreaded oil in the radiator and did the manifold gaskets and was hoping it was sucking air there but no change and did look at all the vac hoses while it was apart. I did replace one but I might have split when removing it.

I can see the cylinders that says knock sensor is active and it shows the negative degrees of spark timing.

A sick injector is certainly a possibility.

Thanks again immortality and everyone else. cheers ;)

I was leaning toward a dud injector but I'm new to this and unsure of what I'm doing and I did order 6 new Bosch (copy's) that turned up yesterday:D So I'll put them in Saturday and see what happens then.. To tell the truth I am a bit worried about using them but can't afford the genuine items:(

I didn't want to hear that really:eek: but it's all cool as I do know it's a risk they are the 4 hole sprayers like I already have installed now and the Omhs tested 13 - 14 each and they look the part but what's inside them?
Today I electronically tested them and they all clicked.
Also the reviews for these where great expect for 1 fella who used them in a VN said they didn't work for him!
