Are you running a decat, maybe it was disconnected for that reason, but surely it would have to be put into the map, if the lambda is disconnected wouldnt it throw it into limp mode?

but the fault is the same as when I fault code checked it last year... I'll dig it out later

I was wondering if it was the coilpacks could you swap them round to see if the misfire changed to a different cylinder (one of the packs new aint it?). Can you get it to misfire whilst revving on the drive before you try this tho.
m0rk said:BlueR - if yours is like the other Jabba'd IHI cars - then the MAF isn't able to accurately read the inlet air flow, so it's relying on the primary lambda sensor to correct for the fuelling at idle. now if that's shot as well - then the car cannot control it's idling at all. it can't tell if it's overfuelling or underfuelling.
replace that sensor (the wires were burnt I recall due to the DP routing) and it should be better....
