i have the code and it is a EVAP emission control leak (small) is what the paper says on it that he gave me the code is DTC P0442

and he thought is may something to do with my cruise control because when i set it it lower 3 or 4 MPH and then shoots up 3 or 4 MPH over what i set it at and it goes back to were i set it

look where the filler neck meets the gas tank. mine threw the same code and it had a small leak there.
