What could possibly cause the battery light and coolant light to come on if alternator is good? Charges 13.5v at idle. I also just recently got a wierd misfire, was cruising just fine and all the sudden it starts to feel like i'm running on 3 cylinders. I had a spare coil and swapped it in had no luck. Very frustrated and really could use some help. Also I can rev the car and seems not to miss but the tach will fall off to 0 but the car is revving. Could a bad ecu possible cause this? I have a msd dis and i have wired so i can bypass the msd and when i do that the car won't even start.
