Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.
Allow the engine to cool if it has been running.

2. Clean the Throttle Body

Tools Required: Throttle body cleaner, soft cloth, screwdriver set.
Remove the air intake duct connected to the throttle body using a screwdriver.
Spray throttle body cleaner onto a soft cloth and wipe down the throttle plate and surrounding areas.
Reattach the air intake duct securely.

3. Replace Idle Air Control Valve (if faulty)

Tools Required: Socket set, torque wrench, gasket scraper.
Locate the IAC valve on the intake manifold.
Disconnect the electrical connector and remove the mounting screws using a socket set.
Clean the mounting surface with a gasket scraper.
Install the new IAC valve and torque the screws to manufacturer specifications.

4. Check and Clean Mass Airflow Sensor

Tools Required: MAF cleaner, torx screwdriver.
Disconnect the MAF sensor electrical connector and remove it from the air intake tube.
Spray MAF cleaner onto the sensor element, allowing it to dry completely.
Reinstall the MAF sensor and reconnect the electrical connector.
