Carbon deposits probably ... being cleaned out by driving. Try revving the engine to high rpm's in neutral for a brief while and see if the hesitation goes away.

If not, time for a BG44K session, followed by a full injector rail flush if that does not cure it.

Does your oil level and pressure appear okay otherwise?

yeah oil pressure is fine and oil level also.
