Weird fuel problem? Help/Advice please!
96 CX hatch. BONE stock y7. New plugs, wires, cap, rotor, etc...
Driving on the highway the other day and my car started misfiring. Pulled off to see what was going on. With the car running, I started pulling the plug wires to see which cylinder was missing and it ended up being cylinder 2. It was dark so I could see/hear that the wire was still getting a very strong spark though it, so I figured it was a fouled plug.
Next day while changing the plugs, which are only about 2 months old, I noticed that all but cylinder 2 were perfectly normal looking. Cylinder 2's plug however was completely black. Put the new plugs in - same problem. Also checked the codes but the only ones on were 02 sensor, CKF sensor, and "Bank 1 too rich", but they have been on since I've had the car, and it's never had any problems at all.
My next guess was that cylinder 2's injector was stuck open, which would explain the completely black plug, and the monstrous amount of gas my car used getting home that night. Picked up a set of 99 Si injectors this morning, put the freshest looking one on cylinder 2 - same fucking problem. Also, when the injector clip on cylinder 2, it doesn't change at all, just like when the plug wire is pulled.
It's got spark and it's got fuel, it starts and runs, doesn't smoke out of the exhaust, but it feels and shakes just like its got a misfire. I pulled the 2 day old plug out of cylinder 2, and its already black. Im stumped.
Any advice/solutions would be GREATLY appreciated as this car is my daily, as I'm sure your Honda is yours. For the most part. Thanks in advance!

^exactly do a compression test first to see if your cyl isnt toast. After that if you have good comp, spark and fuel then my next step would be switching the wiring harness. I have had a similar problem before. I actually cut the wires to the injector then jumped it over with the 3cyl so it would shoot fuel at the same time and it ran great till I bought another harness. This has actually happened to me twice with the ek civic.
