ok i got my code(s), it blinks 1 time and then it pauses and then it blinked 15 times at the same pace and i looked up 1 and it was o2 sensor, and then 15 is "Ignition Output Signal" what is that??? but when i have my MSD 6 series ignition on my distributor cap it starts up really hard.. like it putts and then it starts up barely, and when i take off the wire that goes on my distiributor it starts up like a dream. and i have NOT taken out my stock internal coil, cuz i have no idea how to. so i was just wondering if it does just blink 1 time to say its working or not, and also what is that code 15? thanks
