Hello my name is***** am an ASE Master Technician and I am glad to help you with your question.

This code if for a cylinder 2 misfire. I would check the plug, coil and plug wire first. Check spark with a spark tester, and check injector pulse with a noid light. If you have spark and fuel, then you need to check compression with a compression gauge.
