You've pretty much covered the ignition system,you could have then a fuel, mechanical or vacuum leak issue. Look for a vacuum leak at the manifold or intake runner, check compression in that cylinder see if it is the same as the other cylinders. If possible move that fuel injector to another cylinder see if the cylinder flagged for the misfire follows the injector. There is a company that independent auto repair shops get their information from, this same information is available inexpensively for people that work on their own cars.. The information is year make and model specific, covering repair procedures, torque specifications, fluid capacities and specifications, service bulletins, component locations, wiring diagrams ect.... Alldata is very easy to navigate

Thanks for the input. I pulled the coil pack out of the #6 cylinder and found that the coil pack that I put on when the problem happened the first time was the culprit this time. The plug had somehow burned a small hole in the coil pack. I still had the old one. Put it on and the problem is gone. Now i hope that the aftermarket one that caused the issue was defective to begin with. Only time will tell I guess.
