Need some help diagnosing my Accord it has about 195k miles. Whenever I drive for about 30-45min i get a hesitation and bogging almost to a stall the idling gets rough. It usually when I try keeping a steady speed or a normal take off from a light or stop sign. If I go over 3k rpm it usually isn't a problem. I don't know what to do I have no CEL lights but I did have code p0420 that is because it doesn't have a cat. I also had p0300 p0302 p0303 and p1399. I have changed the fuel pump spark plug wires rotor and cap and also distributor. Ignition switch ignition coil it has a cold air intake if that has to do with anything. Any help would be appreciated thank you!
