Not good then Rob, did any of the plugs look any different ?
Are you sure it's just on idle.
I've got 2 spare fuel pressure reg's if you need to try them.
Could try dicsonnecting the fuel pressure reg vacum hose, blocking the pipe on the inlet. then see if the idle smooths out due to the pressure reg running at atmospheric rather then vacum pressure.
Lambda was reading OK and idle didn't smooth out when disconnected.
Could try cleaning idle control valve.
Disconnect plug leads one at a time and carefully listen to see if you can isolate anything to one piston.
The trick to determine which pot is slaping with piston slap was to do the above. Whan the slap noise goes thats the piston that needs sorting.
Have you got an old top mount kicking aaround. Could bung that on to isolate FMIC and allit's pipework.
