possible coil gone bad

So a few weeks ago the bike started acting funny, i would have it warming up before a ride and it would just drop off. It sounds like it's missing and the RPM's would drop way down. If i start reving it it would jump back up, but then even when riding would drop down and I would sometimes have to shut it down and restart to get it back to running condition.

I thought maybe a gas flow issue but that doesn't seem to be it. This past weekend I starting to take things apart and check them out and am getting really poor spark on cylinders 2 & 3. 1 and 4 get great spark very bright and blue. 2 & 3 are very dim, some troubleshooting I have done are tried different plugs still the same issue on 2 & 3 moved tried moving the wires from one coil to the next and still poor spark. I even moved the coil wires from one to the other and get good spark on the coil for 1 & 4 with the wires from the coil for 2 & 3. I think it's a bad coil but wanted to ask here an see if maybe someone had some other ideas, thanks.
