Fuel Pressure Regulator Questions
Hey guys im getting terriable gas mileage probaly due to a rich running conditon which can be due to three things. 1. exhaust leak 2. "lazy" o2 sensors or a bad fuel pressure regulator. Now my exhaust isnt black or white and running my fuel pressure is where it should be. I am just trying to cut out the incorrect reasons for this bad gas mileage. Any thoughts on this regulator?
