2005 Mitsubishi L200 • 4 cylinder 4WD Manual • 78,000 miles

My 2005 l200 intermittently has a loss of power at 2500 to 3200 rpm, almost as if it was a petrol engine with the choke stuck on, can anyone give me a clue to what could cause this? Mitsubishi want £89 to put on diagnostics but say cant guarantee finding fault, any comms welcome as short on cash this side of xmas.
