Default 2001 4.0 running like crap

I changed plugs and wires after i felt my truck cutting out the other day. I figured it would just be somthing simple. That didnt help at all. when noticed it i didnt have any power and it would barely move when i hit the gas. i plugged it in at the auto parts store and code read that it was a misfire in cylinder two. but after changing all the plugs and wires idk what the heck to look into next. any ideas would be good, the trucks only got 112000 miles on it. if all else fails it will get a 5.0 haha let me know thanks guys

Check for a vacume leak? especialy under neath the throttle body it tends to break on these trucks.

this happened to mine a while back. turned out to be my timing sprockets. but that was resulting in shaking so i dont think this is your problem also. have you checked your throttle body?

A week after getting a new coil pack it started doing the same thing. Just out of luck i tapped on the mass air flow sensor and it ran fine. Just random luck I guess but the truck runs awesome again after replacing the sensor.
