If you have trouble starting your car in winter, it could be that your fuel filter is gummed up. It might work okay when it is warm, but when it gets cold out, all that gunk in the filter thinkens and makes it hard for the fuel to pass, untill you get the fuel running through it constantly. Its good to change the filter every year or so anyways. You'll get more power (not huge, of course) out of your car, and she will perk up faster when you punch it. Plus, fuel filters are fairly cheap.
