cylinder #6 misfire is wut my obd2 code reader says (P0306)...the connection from the wire to the spark plug is fine...checked it a million times and the wire is completely shielded with fire sleeving...my next thought is that the connection on the opti end is not on well (which i think it is), or that wen i crimped the opti boot and terminal on that end...that it didnt get a good contact...anyone else have opinions on what i should check or do in this situation??

 

check the opti end, then check the plug(switch with a different cyl,. see if the miss moves), then check compression, then fuel injector
