Hello,
These codes are misfire codes. These will only set if the engine is running.
But they do possibly point towards an ignition system issue.
My suggestion is to next check to see if there is any spark at the spark plugs.
This can be done by using a dedicated spark tester, a long screwdriver or a test light

See image below for test light sample, these can be purchased online or automotive shops.
