HELP on some OBD II Codes

2000, ES V6.

Check engine light on.

Actron CP9175 scanner from Autozone.

P0300
P0442
P0455

I have been trying to look up some background to these codes, and of course I have the generic description for each one from the scanner, but I am curious of anyone has some suggestions.

Thanks very much to anyone who responds.

P0300 - RANDOM CYLINDER MISFIRE DETECTED
P0442 - EVAP LEAK MONITOR SMALL LEAK DETECTED
P0455 - EVAP LEAK MONITOR LARGE LEAK DETECTED

I would look at your EVAP hoses for splits and cracks.

P0300 - RANDOM CYLINDER MISFIRE DETECTED
P0442 - EVAP LEAK MONITOR SMALL LEAK DETECTED
P0455 - EVAP LEAK MONITOR LARGE LEAK DETECTED

Thanks Rah, will do it this morning.
