Going to chek out my ignition coil packs with a multimeter. Anyone know what the resistance in ohms should be for a good or bad? I've tried searching and just get sites selling new coils. Called Infiniti and they said their techs would have to search online but cant do that at this time. Called some shops and said to look for any burning or bubbling. I've had code p0300 for about a year now. Thinking its coils or injectors
