Hello, everybody. I have a taurus SE, 2006, milage is 51K. the problem is when I step the gas and accelerate, some noise occured. the noise is not very big but can be heard, like sound of wind, seems from passanger side. with the speed increased, the noise become more and more strong. I think the noise may be relatd with the intake valve or something else, because my mpg is very low, less than 23 in highway. so what should I check? Clean the fuel injection system or replace some parts? Thank you very much.
