Question Intermittant misfire

My car is throwing a P305 intermittently

I swapped out the coil pack and still get a MIL intermittently. It seems to happen more often at low /idle RPM.
It does clear from the dash if I click Ok with the stalk, which it did not do before I changed the coil pack. It also threw the code more frequently before I changed the coil pack.

I am pretty sure the plugs have never been changed ( I bought the car with 80k on it), and there is 112k on the clock. I was thinking that maybe from the misfire, the plug got fouled a little and driving with the plug firing cleaned it a bit

Any ideas?
