Whats you mileage and what do you think it should be? Don't guess track it on your next tank so you know an exact.

Well at least you know, your probably below 1/2 a tank of gas hu? Check your vac lines and make sure they are connected. If your egr is bad I would guess its the solenoid. He is a link to where it is, post 2...
