INTAKE MANIFOLD VACUUM INSPECTION
1. Remove the purge solenoid valve from the supercharger and install the vacuum gauge.
2. Verify that the intake system parts and hose are securely installed.
3. Warm up the engine completely.
4. Measure the intake manifold vacuum when idling (no load).
– If not within the standard, perform the following inspection:
 Compression pressure 
Air suction
Each vacuum hose connecting area.
Evaporative hose connecting area.
Throttle body installation area.
Fuel injector installation area.
PCV valve installation area.
Intake manifold installation area
Supercharger installation area
Intake manifold vacuum value
Approx. –60.0 kPa

AIR CLEANER REMOVAL/INSTALLATION
Note:
Do not remove the fresh-air duct valve actuator from the fresh-air duct because it cannot be reused once removed.
Steps:
1. Disconnect the negative battery terminal.
2. Open the engine cover.
3. Remove the left wall (front).
4. Disconnect the MAF sensor/IAT sensor No.1 connector.
5. Remove using the procedure show in the figure.
6. Install in the reverse order of reomoval.
