Engine management - injector problem

Hi, any body help please. I have a 2006 CRD grand cherokee. the engine light is on with fault code P0278 (cylinder six unbalance). The computer and wiring were checked and are fine. If I let the vehicle idle for 15 to 20 min it starts smoking, no loss in drive power however and smoke disappears when driving normal. Light goes down if I drive slow (<40 kph) for long period.
