RE: engine mis

Are you sure the bad mileage in town is not due to red-light-jack rabbitting??

Mustangs are not known for good mileage around town. I can get 21 mpg on highway but if I do city driving all day long I'm lucky to get 15-16mpg and that's a manual tranny. Autos are worse.

Absolutely. If I stay off the highway I may only get 150 miles a tank from my auto. [:@]
