My cel tells me i have a misfire in #2 but nothing else. See below.

What is your question?

I've either replaced or changed around parts. I've put a meter on everthing and everything seems to be working. However, I'm still only getting a misfire code in #2. I don't know What else to do. There is no spark. I've even changef the fuel injectors around. I need some help. Now my truck has no power unless I the pedal to the floor until it changes gear then it keeps going back and forth.
