Bad ignition coils/coil packs usually act up when the car is warm. I'm not saying it isn't possible for cold symptoms but, with my experience, only when the car is warm or hot. The vehicle will run fine then, all of a sudden, it'll spit, sputter, lose power and go dead. Since you have a 4 cylinder, you'd probably never notice a crossfire problem as you would with a 6 or 8 cylinder. A 6 or 8 cylinder USUALLY won't go dead with an ignition coil problem. It'll just bog down (no power) and nearly die when the gas is put to it but they'll lope and rough idle. When the car is cool, it'll start and run fine. When a 4 cylinder crossfires, you're losing 2 cylinders and the 2 that's left isn't enough to run the engine.
