ABS and check engine lights are on, codes PO455/442

Good morning.

the 455 and 442 are evap codes for the EVAP system.

the ABS indicates a fault in the ABS system. you will need someone with a scan tool capable of reading ABS codes to read the fault. a lot of hand helds will not read brake codes, only engine codes.

As far as the misfire, how old are the plugs, wires on the engine?

I will get information on the EVAP codes for you.
