The codes you have are engine misfires.
Code 300 is random misfire (could be any cylinder).
Code 302 is cylinder #2 misfire and 303 cylinder 3 misfire.
Most common causes are ignition issues.
Spark plugs, ignition wires/boots and ignition coils.
Next would be fuel issues such as fuel injectors.
Next would be emission components such as EGR valves.
Then in a worst case condition would be engine wear parts (valves, camshafts etc.)
The place to begin is ignition as this is a common failure on most cars.
