[_paralyzed_]

like I said, cold starts are bad on engines, and although the accord will start, it too should have a block heater. The cardboard is for your comfort, it doesn't help the vehicle. The proper way to heat the engine is with a heater that will replace a frost plug on your engine block. Alternatively, auto parts stores have magnetic heaters you can attach to your block or oil pan. Of course 99 percent of people don't know that and are just fine. My van has a block heater and a trickle charger that gets plugged in at 10 or below. Peace!
