I re-ran the analysis today for ME (O2 sensors specific focus (P200F & P2082), then started the car and reran. Still got there error. I then went into real time data mode and reviewed the O2 outputs.
The pre cat ones are all over the shop, jumping around between 0.15 and 0.7V, whereas the post cat ones are showing 0.7 and 0.65 for Bank 1 and 2 respectively, with very little (+/-0.05) variation. Interesting the difference between banks too.
The fault is coming up from the pre cat ones, and I suspect it might be back again after clearing the codes when I check in a few days.

Will wait and see.

OK - deleted codes and renewed service counter.
Will check later in the week.

Another thing that threw me was the manifold pressure....sitting at 30kPa at Idle (and in Park) and then going up to 160kPa at boost around 2-3000rpm when driving. I'm still not sure what's going on here. Is 30kPaA actually 70kPa below atmospheric? That's a hell of a lot of suck and too much for my mind when air intake is so small a volume at these low rpms. I mean this 70kPa drop is occuring from the point of measurement (manifold) to the inlet of the air intakes.....far too much!

I recall manifold pressures should usually be around 5kPa below atmospheric or 96kPaA.
The 160kPaA seems more realistic for 2500rpm - or 9psi.

Need to get some data capture going on - anything that links into carsoft for realtime logging? Dont want a whole new system - just a lggger to hang off carsoft7.4
