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

I took 12 live data readings owing to fault codes coming so stopped to reset codes...These reading start  from cold and go until tha fans kick in...

Like you say,They are CSV files and you need  Excel or star office to read them

The open circuit lambda is likely to be because I left one unplugged after testing stuff, no concern there

When are you free for me to come and play in daylight?

It was a frigging long day

Are you about either tomorrow or Monday for more playtime?

Why didnt you say 

Its not ignition. Its not Fuel..  Its a vac problem i think.... Thats all it can be...

Hope so, but then again, it was just a misfire...

The brake servo vacuum pipe does come from bank 1/3/5. Think about how the intake manifold ports cross over.

Would be worth blanking it off just in case..

Live data shows quite a high MAF reading, even given the cold engine. I suppose that might not be surprising if it's trying to sustain an idle on 3 cylinders. Look what happens to Bank 2 ST fuel trim before it gives up and opens the loop, too.

Thats the area im thinking too..... Tomo Gonna blank the servo bung...(but with that you move over to faulty servo thoughts) And have a good check of the vac pipes with a suckarometer For a split.
Have a spare MAF but once james unplugged the one fitted it never made much change it just went to the ECU default.
PS: thanks for your input

Yes indeed it shoots upwards!

This would tie in with the theory of it running rich, and the other bank lean, no?

Do you want to leave it until I get there? We can look together in daylight with clear heads

[JamesV6CDX]

I can head up late morning ish

[Steve B]

ok james   and yes MAF reading are a little up from before 

Top is before we played around.... Bottom is now .

[Kevin Wood]

14Kg/h is right on the money for a warm engine. It will be higher when in cold start, of course.

And it can be seen from the bottom pic that our MAF reading is too high at the Moment

So what changed between the two readings?

If there is a serious misfire, I'd expect it to be a little high, as said.
