I did two things that got rid of my "hesitation/misfire":
1) I re-gapped the plugs to .035" (instead of the factory recommended .040-.051")
2) I brought the oil level up to spec, the V-Tec solenoid needs oil to operate (if your V-Tec solenoid is "fried," you will need a new one...~$150).
Hopefully these two suggestions will solve your problem. If they don't, then you might have to replace your coil packs
at ~$250+ just for the parts (Ignition Coil - OEM Part Number 30520PWC003 - Price - $$61.62).
LMK what goes,
BTW, I am at 92K on the original plugs. I just checked the gap yesterday, and they are still where I gapped them. Here is what they look like at 92K if you are interested:
