Learn the specific system operating characteristics of multiport and sequential fuel injection systems.

Examine individual components for each system:

• see how they function,
• discover their purpose,
• and learn how to diagnose them; including idle air control (IAC) and mass airflow sensors (MAF).

Check fuel system pressures and diagnose fuel pressure regulator and pump failures.

Perform fuel injector balance tests.

Adjust minimum air rate and throttle position sensors.
