Check the fuel pressure. Check the sparks, if they are weak, the ignition coils could be bad. Check the ECT.

More fuel than air-rich mixture

Probable causes of an engine running rich are as follows: 1. Fuel pressure not within specs. Can be cause by restricted fuel return line or defective fuel pressure regulator.
2. Defective Oxygen Sensors.
3. Leaking injectors.
4. Coolant temperature sensor out of calibration.
5. Restricted air intake system.
