Swapped the intake (with injectors and fpr) over, and spent a bit more time with tech2 on it.

Let it warm up enough to go closed loop this time.

Cyl cut-off - kill any of 1/3/5, and the think nearly dies.

Kill 2 or 4, noticible difference in rpm, but not massive (nowhere near like any of 1/3/5). Kill 6, only a marginal difference, possible none (hard to tell for certain, as defo misfiring, and idle not smooth).

Would the EGR purely feed 2/4/6?

No. I think there's a channel that runs from the EGR valve to the centre of the underside of the plenum, then forward to open out into a port behind each of the throttles.

My elimintation was going to be to remove valve, and start engine with my hand blocking the opening ::).  Maybe should rig something better ::)

Drop of oil brings it back to 'green' (can't remember reading).  After a bit of running, it drops down to about halfway between 0 and start of green.

If compression is brought back with a drop of oil, could this indicate a ring problem?
