FORD C-MAX FUEL PRESSURE PROBLEM

2004 Ford C-Max • 55,000 miles

Black and white smoke comes out when changing gear. When in 3rd gear feels like it loses power. Also put redex in Engine.

Sounds like its running to rich due to the following below

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.
