Will be doing fuel filter tomorrow and will go from there. Anyone running a rising rate FPR and if so what is your idle pressure set at ?
Idle pressure should be set to 3 bar with the hose disconnected.
Have done the regulator and done fuel filter today with no change could it be a bad Maf?
Do you have any fault codes at all? If a sensor is failing, it could cause similar issues. Different vehicle I know, but I had a misfire in a similar RPM range on the RVR with a dodgy cam position sensor.
In any case, fault codes is a good shout if you haven't already pulled them

Why not become a full member of CVR4 and enjoy the additional benefits membership brings?! Information here.
If the plugs havent been done, then it's no bad thing to do as a matter of course anyway.
The rear bank generally gets hotter anyway, so can accelerate general wear and tear in that region compared to the front.
Also, some less-thorough owners/garages have been known in the past to change just the front bank plugs, as it only takes minutes compared to the additional time involved in removing all the gubbins required to access the rear bank, so unfortunately, the condition of the front plugs is not necessarily the good indicator of the condition of the rear plugs that you would hope it to be!
Plugs
Thats why Mitsubishi quote several different plugs for Front Bank and Rear Bank as standard (also depending on location/country)The rear bank generally gets hotter anyway, so can accelerate general wear and tear in that region compared to the front.
