P0306 means that the cylinder 6 plug isn't firing properly, either due to a bad plug, wire, or coil. I may also involve vacuum leaks or fuel delivery problems, but is usually related to the electrical system. Check out the coil over plug boot, if the car has a lot of miles, it might very well be just the boot leaking due to oil or water intrusion, or a crack in the boot. It is possible that the coil has a short, but it might just be dirty or otherwise crudded up. Hope this helps!
