Hello there.
P0304 means cylinder 4 is misfiring. It can be caused by many reasons from a faulty ignition system, fuel system, or internal engine failure. The most common reason for this to happen is faulty or worn-out spark plugs, spark plug wires, ignition coils, fuel injectors, compression, or vacuum leaks especially if it's been a while since you had a tune-up.

If you can't diagnose the problem yourself, it's recommended to take your Nissan Frontier to a qualified mechanic to determine what part needs replacement.
