So i finished my top swap and the car ran great and now this p0306 engine misfire code is popping up for cylinder 6. I have new spark plugs, i bought a new ignition coil pack, and have swapped plugs around to see if it would switch codes. O and i also switched injector When i switched the spark plugs the misfire one had a black tip and the one i swapped it with had a white tip.
 


I haven't checked the compressionet I'm hoping I can have a shop look at it tomorrow. What's the worst possible scenario? I don't think I'm burning oil or coolant cause smoke isn't coming out of my exhaust. I am running straight headers though with o2 unplug, could that cause this? Could it be a broken valve spring?
