Why does my check engine light come on throwing a code saying its misfiring. Then the light goes off amd it runs fine

What is your question?

Showing a misfire on number 5 feels and acts like a misfire. Then my check engine light goes off and it runs fine.

What makes this problem better or worse?

Acceleration makes it worse while light is on

How long has your 2009 Ford Escape had this problem?

Few weeks
