Thats way too little info for anyone to really help you. What does "struggles" mean? Its hard to crank, it idles poorly, or you are losing power, what issues are you having? How many miles do you have?
My generic answer would be to get a tune up, or fuel injection service. You could clean your MAF sensor. Who knows, post more info.
I'd check the battery too. After having my the first battery in the car for several years... it reached the point where when it was really cold that the car would sound like it was really fighting to start. Once I got a new battery it started up right away!
