Engine Mechanical Component Tests

1. Verify air intake hoses are installed properly.
2. Start the engine and run it at idle.





3. Measure the intake manifold vacuum using a vacuum gauge.

- If not as specified, inspect the following:
- Air suction at throttle body, intake manifold and PCV valve installation points
- Fuel injector insulator
- Accelerator cable free play
- Engine compression.

Specification:
More than 60 kPa (450 mmHg, 18 inHg)

NOTE: Air suction can be located by engine speed change when lubricant is sprayed on the area where suction is occurring.
