Performance Verification

NOTE

If you do not have at your disposal a special device for testing fuel injectors, follow the "Test of fuel leakage" to check the serviceability of the fuel injector.

Disconnect the negative battery cable.

Remove the fuel injectors.

Connect the fuel injector tester to a fuel injector.

Measure the amount of fuel injected by each fuel injector, using the graduated container. If the amount of leakage exceeds the norm, replace the fuel injector.

The amount of fuel injection:

L3: 61-71 ml / 15;

LF: 53-69 ml / 15;

L8: 48-63 ml / 15 seconds.

Turn the ignition key to LOCK and remove the jumper.

Install the nozzle in place.
