Td5 110 pulling away

guys , as above , sometimes when starting and driving away it’s sluggish , first couple of gears as if not firing on all cylinders or fuel starvation, doesn’t stall or not go just doesn’t clear it’s self to pull cleanly away
Recently put on new injector harness and cleaned ecu box , new fuel filter , still the same
No problem with starting , drives normally once you’re away , any thoughts ?
Thanks all

Fuel pump on its way out is my guess,

MAF unit faulty?

Unplug MAF unit and see if it's any better, if so it's faulty.
I had a similar fault with my 110 TD5 and it was the MAF unit.

Thanks guys will have a look today
