Freeze frame P0304 hyundai tucson 2L 2008

Hello I am having a missfire on 4th cylinder a while now and it bugs me as the car seems to run normal but the code kepps coming back.I recently got an ancel a410 scanner and I cleared the code twice so I can get the engine light back on and see the freeze frame data of the code.Changed spark plugs cables and spark plugs checked my MAF and swap position of the coil pack to see if the issue goes to another cylinder.It seems to me that any time I clear the code it comes back around every 100-150 klm and when the engine is cold at idle.i ll post here later today the numbers of the freeze frame I got to times in row.One question before I post the numbers.Can a leaky fuel injector that drips over night when the car is not running makes the mix to rich in the morning and gives me a missfire? Because I remember for sure both freeze frames gave me between -5 to -8 short term fuel trim p.s. compression is 180-179-178-180

Given those compression numbers and the fact you did a coil swap and new plugs and wire… I’d do a fuel injector swap and see if it follows, especially if the #4 plug was a bit black when it came out.
