Could be a number of things. What is the condtion of the spark plugs and wires. If they are old they should be changed either way. Is there spark at that cylinder?

Spark plugs and wires were replaced about 6-8 months ago. Never had a problem with it until I moved from new jersey to wisconsin. Could the cold weather be a part of it?

What kind of fuel are you running in wisconsin. Might want to pull that injector and see if its clogged, and swap it with an. Other injector to see if the misfire travels to another cylinder
