The code is p1399 and it’s for a 2000 Honda accord if anybody out there can help me figure out what this code means before I go to the Honda dealership it would be greatly appreciated.

google it for a while - Honda apparently has this extra mysterious random misfire code that apparently doesn’t even show up on a lot of ODBII code lists. i also saw some reference to it pointing to the EGR valve

The DTC P1399 is for: “Random or/and multiple cylinder misfire detected”. DTC P0300 is for: “Random [cylinder] misfire detected.” Note the difference.
There are other, and less expensive, mechanics available than at the dealers. Oh, well.
