my car was driving fine all day, it’s been -40 the past few days and I’ve boosted a couple of people’s cars. Just last night I was driving and then parked my car in my driveway then the lights started flicking and engine was sounding like a four wheeler, then I drove up the road and it stopped shuttering but the rms weren’t normal and Every time I slowed down the car would shutter again then it **** off at a red light battery light flickered on and off then I turned it on again and it shuttered again and I parked it. I’m thinking it could be my coils/spark plugs. Or my battery. My buddy is coming on Wednesday with a scanner and voltage tester because it’s going to be -6. I’m just observing if someone has info on my situation?
My audi has 152,000km on it
