Still no improvement

Tried the suggestion on the Land Rover forum, and apart from the obvious change in process the result is the same. The best way I can describe the idle issue is that it never seems to settle, including the stepper position. Took the car for a long-ish drive and the misfiring under load is still there.

The plugs and leads were only replaced at the end of last year and look to be good quality and ok in condition. Short of replacing these again, I'm at a loss as to what I can try next. Unfortunately, the MOT is due this week and I suspect that it'd fail on emissions if tested as is.
