1999 Honda Cr-V is burning raw gas, and a cylinder is not firing. Any ideas on what the problem could be?

I recently purchased a 1999 Honda CR-V for a low price due to a miss in the engine. After replacing spark plugs, wires, Distributor Cap/roter, and ignition coil, the problem continues. I had suspected the fuel injector was bad, but the CR-V is made is such a way that checking the injectors is harder than it should be. Giving codes P1399, and PO304. This is because cylinder 4 is not firing at all. Pulling plug wires while the engine idles shows that pulling cylinder 4 has no change. Swapped park plugs and wires with a different cylinder and they work fine. Raw gas and black residue on exhaust pipe. Has a hard time when starting up, but once the engine warms up it runs perfectly. Shuts off when put into reverse before engine is warmed up, RPM too low.
