2000 Honda Accord 3.0 Automatic. Everything fine. Then lost power. SUrges at idle and all 6 cylinders have misfire codes as well as P1399. If the rpm is increased the engine stops surging and runs smooth. Codes are all the P030x codes and P1399

It sounds like the EGR valve may be stuck open. I have seen them fail causing a misfire and driveability issue at lower RPM's. Remove the EGR and see if the valve is closed all of the way. I have included a picture of one that's OK and one that's stuck open.
