Check connections at coil pack/packs and perhaps have a look at the plug/plugs. I took it to a 'reputable' mechanic shop and they performed a tuneup to fix the misfire on cylinder 6. Misfire the next morning if car runs only for 15 seconds. Misfires are solely the result of either advanced or retarded cam timing, as the ignition is firing either too early causing what is known as premature ignition, or. Infiniti G35 With 10. Oil leak and a Cylinder 1 misfire. The misfire moved to the cylinder that I put the coil on so I knew that was the problem.
