po300 went to the track lastnight ran 3 times everyone had a multiple misfire code car would pull hard and my time got faster on every run but the 1000 ft time stayed about the same seems like i was getting the misfires shifting to 3rd i assume its a bad plug wire checked the plugs

multiple misfires ran 3 times at the track every run had the multiple misfires reset the pcm think i have a broke rocker arm fixing to go pull the valve cover would that cause the p0300 misfire?
