noob needs help with mileage

noob needs help with mileage - only 10 MPG!

I finally burned thru a whole tank of gas and calculated the mileage:
13mpg (mix of city and hwy)

I was hoping for 15mpg or better, but 13 is sure beats 10.

Does it still run rough like you said initially? Mechanical problems usually don't fix themselves.
