- Scanned computer for codes and found 3 present. Fuel system lean is likely the main issue and caused the misfire. Began testing and found when accelerating the computer is adding up to 25% extra fuel. With vehicle at idle the computer is adding 12%. Test system for vacuum leaks and found none. Test fuel pressure and found pressure at 35 PSI. Upon reving up the engine pressure decreases to 30 PSI. Spec for this vehicle is 43 PSI. When unplugging the vacuum hose to the pressure regulator pressure is supposed to increase about 5 PSI however only increases by 2PSI. Recommend starting with replacing the fuel pump and fuel filter. If this does not solve the issue completely the regulator may also have to be replaced.
