Update on the misfiring and low voltage situation.
I did a deep scan on the car and found 2 codes related to the battery current sensor. I’ve never heard of this thing but it’s a sensor in the negative battery terminal wire that essentially communicates the load to the ECU and then the ECU tells the alternator how much voltage to pump out. Well my car is missing that sensor. I ordered a new one and am expecting it in any day now. After reading up on the sensor all the symptoms I’ve been having match up to everything that this sensor controls, even down to the power draw when the cars off. My only concern is I’ve had the car for 3 years and it’s been boosted for 30k miles, I’ve never taken this sensor out myself why did it wait until the last 8 months to get this bad a reveal itself?? Hoping this wire is my problem
