I suffered the same intermittent faults until I started using injector cleaner fluid at regular intervals. I too went to a main dealer who spent all day with no result checking diagnostics etc. they could only make expensive suggestions about changing bits but with no guarantees. After using the injector cleaner the engine now behaves itself.
