A misfire and low compression on the same cylinder are indications of an internal engine problem. You need to do a cylinder leakage test. That is where you set cylinder at top dead center with the valves closed and apply air pressure down the plug hole and see where it leaks out. If it leaks out the exhaust pipe the exhaust valve is bad etc.... If you haven't performed this particular maneuver before, and don't know the potential problems, you need to be VERY careful. When you add compressed air the engine will turn and if you have anything resting on the serpentine belt or any other moving part, it could get caught and cause damage. Low compression can also be the result of "blow-by" (caused by worn or sticking rings) or by a leaking head gasket (caused by a warped head when the engine overheated).

If check engine light is on, have a parts store read the code. It will tell you there is a random misfire and usually what cylinder is misfiring. Replace the coil pack for that cylinder and all will be well.

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.
