Take it to another shop and have them do a compression check. If the compression is low, you have found the problem. If the compression is the same as the other cylinders, trade the fuel injector at that cylinder with another cylinder and see if the problem moves. If the problem moves (misfire code in different hole), the injector is bad. If the problem didn't move, and the compression is fine, then you have a vacuum leak on the intake runner to that cylinder, possibly the intake gasket. Print this and give it to your new mechanic.
