I can tell you the car is running fantastic (for an 10+yr old car) and the mileage is just fine. I still fill up my 10 gallon tank once every two weeks (and I drive 40 miles a day. Though my head is tired...I can't think of the math for MPG right now.)
EDIT: 40 MPG. Took me a minute, but I got there. (That really shouldn't have been hard, now that I think about it!)
a lot of these guys prey on young women. its too bad you dont know someone you can really trust with this. if it was me, id just keep driving it. my check engine light in my truck has been on for over 2 years..... or, have a guy take it into another shop and see what they tell him?
