Whats wrong with my 2002 merecedes c240?

Question

The car hesitates when trying to start and it sounds like it is trying to turn over-sometimes after a while it does and sometimes it doesnt. Also, the car idles very hard when stopped and in some cases when sitting in traffic it will stall. When on the highway it will slow down on its own, like it's dying, it loses all its power no matter how hard you push on the gas. You can only go about 35 mph in this case. What do you think is wrong with it? I do not have the money to take directly to the dealership. Thank you in advance for any advice you can give! =)
