I've changed plugs, wires, and coil pack...still getting the code. What else could cause it?

have you tried moving coils around to see if the misfire moves? if doesn't move and is still misfire on #4 then I would suggest to replace the ICM. ( the plate that the coils sit on)

I had a misfire on 6 turned out to be an intermittent fuel injector. While in idle it has a slight stumble. However step on it, the stumble was horrible. Felt as if the tranny was falling off.

I've changed the coil pack on cylinder 4, I think I changed the plate under the coils not that long ago. I sometimes have a stumble at idle, I've been getting worse mileage by 2-3 mpg. Sometimes feels like it's not making the power it should.I've been thinking of changing the injectors. Any advice on where and what to get?
