Mitsubishi L200 intermitent missing of the engine

Car: Mitsubishi L200
Variant: 2.5 manual
Model Year: 2005
Categories: Running Rough, Starting & Power Loss
when I get to between 2000-3000 rpm and the engine is warm it appears to mis-fire or intermitently lose power or go onto 3 cylinders. Its had a new egr valve fitted, a new fuel fitler, a new air filter and a diagnostic hasn't shown any error codes. Any suggestions of what I can try next???

Hello Andy, I used to sell these pick ups at a mitsi dealership, If its the new shape l200, they have a system built in which re writes the programme in the ecu, to the most recent driving style.while the ecu is going thru this upgrade they do run rough for about 3 or 4 minutes but should then return to normal operation. Hope this helps.
