Probable causes of an engine running rich are as follows:

1. Excessive fuel pressure can be cause by restricted fuel return line

2. Defective Oxygen Sensors.

3. Leaking injectors and fuel pressure regulator.

4. Coolant temperature sensor out of calibration.

5. Restricted air intake system.

PLS ADVICE: THE PROBLEM IS IRRATIC WHICH OCCURS AT ANY TIME. WHEN THE PROBLEM OCCURS THE POWER DROPS AND MISSES CAUSIN HEAVY WHITE SMOKE. COULD THE BREATHER OF THE ENGINE BE FAULTY OR THE EMS SENSOR?
