what's up man, you have some high hopes, which is awesome. the tuning usually doesn't begin until you see occasions and them move along without mercy cool.gif . the P0442 code is from one of your sensors. if everything is stock, you want to go to the dealer and get one of the sensors replaced.

^^ heck no, every sensor is easy to replace on our cars..
Your code is evaproative emissions control. Usually it means that you need a new fuel cap. I
f it were IAT or Power steering you'd throw another code with it. You can safely assume that the correct fuel (low grade) is being used. Engine coolant temp would throw a different code. replace your cap, and check for loose wires on your sensors. the evap canister might be the problem but not likely unless you did something to the gas tank or the canister itself. They don't go bad often.
