Google tells me it's something with the valves. Some people on the interwebz suggest it might actually be normal for that car.
I'd suggest what gunner said to be the best option for you at this point though.
If you've never done spark plugs you could google how to do them and see if it's something you want to attempt. If you don't have to take half the car apart to get to them, it shouldn't be very difficult for you.
