Replacement of the fuel pump would be the case here,unless the fuel filter needs to be changed.To find out,remove the fuel filter,and blow threw it with your mouth,kinda tast bad but it will tell you if the fuel filter is restricted.You should be able to blow threw it easy.
These trucks have a drive by wire system,we seen a` lot with a broken ground wire on the rear of the drverside cyl head,this is hard to see just feel and give the wire a tug .If the wire is loose or broken the reduced engine power light will come on.
Try looking at the idle/air control valve - Look around where the gas cables attach to the engine. remove the wires and then unbolt the unit from the engine. The control valve has a spring valve that you can clean with intake cleaner. re-install the valve and drive to warm up the vehicle. After 20 minutes the vehicle should Idle. If not clear all codes and relist them here - hope tthis helps
My name is Juan Heredia and I'm an ASE certified technician. I have seen this code and this driveability issues before, I will need a little more information about your car to tell you exactly what your problem is, Honda has two different types of throttle bodies for this especific vehicle, drive by wire and cable operated, if your vehicle uses the drive by wire type I would highly recommend to replace the throttle body actuator, if it uses the cable operated one it will be necesary to do a little more testing, let me know if this helps
