Okay. It was the coil that was fixed not the piston. That makes more sense. The airflow thing that you're talking about is probably a MAF sensor. Well, you still have relatively low miles on the car, so you shouldn't have any major issues to worry about. You should double check to make sure that your timing belt was changed. If not, you defenitely need to get that done. Also, check to see the last time your anti freeze has been drained. You should do that about every 3 years. Go to Walmart or an auto parts store and pick up a bottle of coolant system conditioner/lubricant and add it to your radiator when you get it refilled. They'll know what you're talking about at the parts store. Basically, it's a lubricant for your water pump. A lot of people don't realize that you need to do that. It will keep your water pump from going bad on you. Double check and see if they replaced your fuel filter as well. Get that done if not. Also, see if they replaced your brake pads when they cut your rotors. It would be worth it to have them changed if they didn't. Bad pads will just ruin your rotors all over again. That's all that I can think of off the top of my head. Check into those things and let me know what you come up with.
