Just got H23A VTEC swap done. Misfire codes

P1399 (P)

Swap finished last sunday, and I have been having these codes since I got the car back. The car sometimes bogs slightly in lower RPMS at WOT or close to it, but not in higher rpms. The flashing CEL only starts flashing when I really get on the throttle at 4k+ RPM. It stops flashing a few seconds after I let off the throttle. The guy who did the swap thinks it is my fuel injectors. He used my h22 dizzy and the h23 fuel injectors, along with h23 intake mani (top part of mani is h22). I have brand new NGK plugs and wires installed. Tried swapping the old wires and plugs from h23 and did not solve problem. Suggestions?
