Have a mechanc repair the misfire on cylinder # 2, if it is still misfiring, it will not clear up until fixed! After repair, the codes can be cleared to turn off the light.

this vehicle has wires so it may be plug wire. also this car has a history of the coil dropping cylinders so get it to a shop that can put it on a scope to see if it is a wire or the coil.
