i suspect that your Accord has on-going leaking injectors problem
leaking injectors will cause the EGR valve, catalytic converter and
EVAP system to fail, and result in poor drivability and bad fuel
economy
inspect and fix the injectors first, a bottle of fuel system cleaner
may do it.
you dont want to buy another cat for the next emission check, yes?
