Re: misfire issue
Tell us the model and year of your Accord and we could be more specific.....
recheck your engine codes and post up the exact numbers that you are getting. They can be very helpful with diagnosis. A general misfire could be the EGR, a specific cylinder misfire could be a fuel or spark issue.
Have you tried unplugging the EGR or testing/replacing the EGR? It can cause misfire issues.
Now if you are also getting specific cylinder misfire codes you could look at the following;
• Ignition coil
• Spark plug wires, distributor cap and rotor button
• Fuel pressure
• Fuel injectors
• Fuel filter
• Low compression in the cylinder
• Improper valve clearance
