The symptoms are familiar , I suspect a faulty EGR valve, other Honda models had the problem of hesitancy prior to acceleration and the fix being a new EGR valve, often under Honda warranty.
The problem iof hesitancy is most noticeable after coasting with the foot off the accelerator pedal, then applying accelerator. The EGR has a potentiometer which is read by the ECU, when the EGR potentiometer is failing, the ECU has difficulty in reading the EGR signal and hesitates for a second or so before applying power.
