All, just wondering if I could get any help or tips on why my gas MPG has dropped almost 20% over the last 2 months. My check engine light has not come on, I have performed all maintainance up until now - car has 55K miles on it. The only clue I have is that when I first start the car in the mornings it makes a "whoofing" sound every 2-3 seconds as it is idling. Once I make it to the end of my driveway and head out the whoofing is gone. I used to get 20-21 MPG like clockwork but now am getting 16-17 MPG.
Any ideas?
Thanks
