Inside the cab under the drivers side

What is your question?

Truck failed emission test at the smog. I replaced the rotor cap, spark plugs ect. But still has a problem. Put a new Egr in. Nothing changed. Truck has a crack before the o2 sensor, timing is off by 10 points. Was wondering why im still having a problem trying to pass smog. The smog people told me that my car is burning "Rich".
