You can disconnect the vacuum line to the fuel pressure regulator on the fuel injector rail to see if fuel comes out of the regulator. If it does, then replace it and change the oil and filter and clear the codes. If no fuel is coming out of regulator, then have fuel pressure tested to see if one of the fuel injectors is stuck open flooding the engine. Then, replace the fuel regulator or leaking injector. Try to scan the vehicle and compare readings of the sensors to specifications. The mass air sensor may be causing the excessive fuel problem.
