Probably a clogged fuel injector or fouled/burned spark plug. Less likely: valve problem.

Will a burnt valve make the cylinder misfire all the time or just intermitterly?
A burnt valve will cause the cylinder to either be week or misfire completely. Depending on how much compression is present. Sometimes after reaching crusing speed it feels as tho the cylinder is pulling it's weight, this is not true. The only way to correct this is to pull the head and do a valve job. I would reccomend doing both heads at the same time if applicable.

What could cause a misfire on one cylinder after changing plugs wires ignition coil fuel injector and compression is at 180 pounds per cylinder and spark is getting to the cylinder?
I would make sure power is getting to the fuel injector use a noid light to test it. You may also want to check the fuel pressure also the intake manifold may have a leak that can cause a misfire as well. Glad your compression is good. That is a sure sign its something simple.

What could cause a 2001 Ford Focus DOHC with good spark plugs and wires to misfire in cylinder 4 when driving and cause stalling stumbling and P0304 CEL code?
Have you checked the injector? Try switching the plug and/or wire to another cylinder to see if the misfire travels with them. That check engine means cylinder 4 misfire so I would still check the gap and make sure that the spark plug is good even though they are new another suggestion is the coil pack. And a much less likely suggestion is that you lost compression but that's easy to test just take cylinder 4 spark plug out and put a compression gauge in and manually turn the motor over by the crankshaft.
Can a bad spark plug make your car hesitate?
Yes, very much so. If you can check via a code reader which cylinder is misfiring try swapping the plug in that cylinder to a different cylinder and see if the misfire shifts with it. Failing that it could be a cool pack or ignition lead at fault.
