I owned a used car dealership for a decade. FORD vehicles re notorious for not passing emissions because thier engines burn dirty. Check your CATALITIC CONVERTOR/O2 sensor. Go to any MIDAS or MIENEKE, they do free inspections.

Also you might want to use a mid or high grade fuel the octane rating is how complete the fuel will burn and how fast. 93 octane fuel burns almost 100 percent and burns twice as fast as regular. some ford vehicles have high compression engines and the will spark knock using regular fuel and actually recommend that you use mid to high grade fuels.
