Replaced the coil pack a few months ago in cylinder 1 as I was having some very poor operation. Stuttering and jerking. Well this seem to cure it but now I'm getting an engine light again reading the code and here we go cylinder one misfire detected. As well as a p0326. I'm at a loss once again if anybody out there has a clue. No red flags under operating that I can tell In this moment. The AutoZone print out says most likely solution to be clean fuel injectors. I don't know but I don't think this is likely the case.
