vacuum leak or bad coil, start by trading the coil for number 4 to a different one.

Thanks for your input, I forgot the mention that, I have replaced the coil packs when I replaced the spark plugs.

A vacuum leak can and will cause a misfire.

Got it diagnosed by a shop. Said that #4 fuel injector wasn't functioning. Changed the injector today. And codes still showing up for #4 misfire. Any thoughts? There is spark going towards the spark plug.
