Do you have a scan tool? If so you can loom at misfire counts and see if it is still doing it. If you do not have a scan tool unplug you battary for awile and see if the code comes back it could just be a result of the coil you cleaned if 6 was misfiring and you fixed that it could have saved the random code misfire code. Did you every have p0306 and p0300 at the same time?

at first it was a p0306 now its just a p0300 code ive erased it and it popped back up again so im going to check my vac lines and seals and ive already ordered a new coil pack to replace that one so we'll see how it goes from there
