1999 V6 MPG
So... I have this 1999 v6 5 speed mustang that's been setting in our garage for about 5 years. It has 134,000 miles. I just put in a new fuel pump, fuel filter, k&n cai, cleaned throttle body with throttle body cleaner, cleaned maf sensor with maf cleaner, replaced the 15" stock wheels/tires with 17" x 9" ford cobra r wheels with 245/45/17 on front and 255/55/17 on back and the best wheel alignment garage in the area performed the wheel alignment. The spark plugs and wires were replaced 6,000 miles before putting in garage. I've now ran 3 tanks of gas through the car.
I sold my van and decided to put this mustang back on the road to drive to and from work. The car used to get anywhere from 24-27 mpg depending on how heavy your foot is prior to putting it in the garage. Now its getting 20-21 with driving around like there is a egg between my foot and the gas pedal.
Would those wheels/tires make that big of a difference?? If so they are gonna have to go! lol
