From stone cold, through until it's warmed up, at idle rpm

Ok james ...live data gives you about 3 readings per second.... Thats a lot of data to put up 

Just do as much as you reasonably can from cold...

I'm thinking tomorrow or Monday for another look

[Kevin Wood]

Just upload a CSV / Excel file somewhere with all the readings in.. assuming you're using the reader that shall remain nameless.

Yep your correct.. Which reading do you want up owing to there being a lot of them and screen shot will be very very wide

[JamesV6CDX]

Fuel injector durations. I must be honest, I don't remember if I checked these

If it's any use I should have a 2.6 throttle body and fuel rail gubbins in the shed that can be in the post tomorrow if it's any use, postage cost only !

Thanks very much for kind offer

I have spares here for testing purposes but, if I end up giving them to Steve, can I take you up on that please, as I will need them for my project

[Steve B]

Right here we go this is from start with codes cleared until dash light starts flashing 120 mins 

Knock sensor is always inactive and voltage is Nil on both banks

P0161 O2 Sensor Heater Circuit Open (Bank 2 Sensor 2)  is there instantly..then the codes for the 1,3,5, cylinders..

This is the best way i could get all this info on screen

So it purrs at 2000 rpm but 1/3/5 misfire dreadfully at idle?

1/3/5 are the same side as the vacuum connection for the brake servo - is there an uncontrolled air leak ? (nut loose / pipe cracked / servo faulty)

If there is air entering through the vacuum connection then the ECU would close the throttles to control the idle speed which would make 2/4/6 run rich and 1/3/5 run lean (until it tried to run closed loop using the lambdas))

That pipe from servo goes in the other side with the 19mm/17mm nuts

OK - I may have got my banks muddled  so 1/3/5 will run rich and 2/4/6 run lean. Either way the drivers side will get starved of air and the passenger side will get unmetered air via the vacuum hose. (if that is the problem)

[05omegav6]

Yup with it missing you might not hear the leak

[Steve B]

Yup with it missing you might not hear the leak

And you would have a rock hard brake pedal..

Don't bank on it... With the engine running and that pipe vaguely attached, the air pressure in the servo will be lower than atmosphere so partial vacuum will offer some assistance

Deffo gonna have a look around at that area to see if a small split or something... It was dark when we finished ..its got to be something minor like that i think
