I've got a 2g gst and I live in Kansas. Any time the temperature drops below maybe 40 degrees the car has difficulties staying running. I notice the lights on the dash are not as bright as the first symptom. After that it starts misfiring and sputtering. After that it dies altogether and wont start leaving me stranded on the side of the highway. Is this just a poor charging circuit? I know our alternators aren't the best.
