My car has been running like **** lately. It is all stock and has 35500 (hard) miles on it. I want to give it a really good tune up. can some one give me a list of everything I should replace. I know the owners manual has a list, but I wanna here from people who own the car. I want to replace things that might be causing my car to run poorly, since I plan on trying to get it on a dyno. By the way how much does a dyno cost?
