2005 Mitsubishi Lancer Evolution L4-2.0L DOHC TurboSECTION Learning Procedure For Idling In MFI Engine
LEARNING PROCEDURE FOR IDLING IN MFI ENGINE
PURPOSE
When the ECM is replaced, or when the learning value is initialized, the idling is not stabilized because the learning value in MFI engine is not completed. In this case, carry out the learning method for the idling through the following procedures.
LEARNING PROCEDURE
1. Start the engine and carry out the warm-up for the engine coolant temperature to reach 80°C or more.
2. When the engine coolant temperature is 80°C or more, the warm-up is not needed if the ignition switch is in ON position once.
3. Place the ignition switch in LOCK (OFF) position and stop the engine.
4. After 10 seconds or more, start the engine again.
5. For 10 minutes, carry out the idling under the condition shown below and then confirm the engine has the normal idling.
^ Transaxle: Neutral
^ Operation in ignition-related, fan and attachments: Not to be operated
^ Engine coolant temperature: 80°C or more
NOTE: When the engine stalls during the idling, check the dirtiness (on the throttle valve) of the throttle body and then perform the service from Procedure 1 again.

- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
