My issue: Engine code P0302 cylinder 2 misfire.
For P0303/P0304 you will need to remove air intake hose to gain access.
Symptoms:
1.) Harsh startup and RPM would fluctuate between 1-3k no matter if the engine was hot or cold.
2.) Running rich and strong gas smell
3.) Horrible MPG
FIX:
Step 1:
I would recommend to start here first. I changed the spark plugs on all 4 cylinders with oem Motorcraft plugs and erased the code; Still a harsh startup and idle and code reappeared shortly after (you don't need to replace all of the spark plugs, just the one that is misfiring. It was time to replace all of them anyways)

Step 2:
If new spark plug(s) doesn't fix the issue, I would then install a new ignition coil and erase the code.

In my case, I no longer have a harsh startup and code hasn't reappeared. I drove it around and it runs great. No strong odor of gas and MPG's immediately increased to normal amount.
Hopefully, that is all to it for you as well. If not, then it is time to take it to a professional.
I hope this video helps!
