Recently changed the spark plugs and wires. About a week or two later the check engine light came on. The code reader is saying it is a cylinder 2 misfire. We have checked the plugs and they seem to be fine. Anything else we should check? Is it safe to drive with the light on?

You didn't get the plug wires switched around? Check spark--fuel-- compression at #2 cylinder. You can use a spark tester to check spark at #2 cylinder. Pull spark plug wire, stick tester in boot, ground/touch metal part of tester to metal part of engine, watch for spark engine cranking, no need to start it. The autostore sells a spark tester, it don't cost much. You can use a known good spark plug for testing, don't pull one from engine.
