1998 Honda Accord 6 cyl Front Wheel Drive Automatic 99K miles

I have a 1998 Honda Accord V-6 Auto. It has 99k and the timing belt was replaced @80k. It's ran perfect till the other day when it started throughing codes like p300, p303, p304, p306, p1399, p1457. So I did a major tune up on it! I replaced the EGR, Cap, Module, Rotor, Plugs, Wires, and Thermastat, but it didn't help. I've tested The Cam and Crank sensor and they are fine. Coolant Temp Sensor/Switch? O2 Sensor? Injectors? I'm sure the answer will help a lot of Honda Owners.

Simple thing to check is the air intake system. Make sure that the filter is clean. After that I would suspect the fuel delivery system. You could have had a bad run of gas in the tank. The injectors could be dirty. Any number of things related to fuel including the fuel pressure.
