Service engine soon . Code said it was cylinder 7 misfire . What all should I look for that will cause this problem.
Most misfires are caused by ignition issues - such as a spark plug or ignition wire that has failed or has excessive spark leak.

You could also have an injector issue, but I'm pretty sure you'll find your issue on the ignition side.
