I have a 1991 Nissan 300zx tt. It was misfiring but if was every once in a while. I took plugs out regapped them to .034. Then checked the resistance of my cool packs. They are all 1.5 ohms. Then listened to to the injectors and they sound operational. After I did these small things my misfire is very consistant now, not power and it sounds like a motorcycle... I need some help!
