Solution

1. Preparation

• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the negative battery terminal for safety.

2. Clean the Throttle Body

• Tools Required: Throttle body cleaner, soft brush, microfiber cloth.
• Remove the air intake duct connected to the throttle body.
• Use throttle body cleaner and a soft brush to clean the throttle plate and surrounding areas.
• Wipe down with a microfiber cloth to remove any residue.
• Reattach the air intake duct securely.

3. Inspect and Clean the Idle Air Control Valve (IAC)

• Tools Required: Socket set, IAC cleaner.
• Locate the IAC valve, usually mounted on the throttle body.
• Remove the IAC valve from its housing.
• Clean the valve with IAC cleaner and inspect for damage.
• Reinstall the valve ensuring a secure fit.

4. Inspect the Mass Air Flow (MAF) Sensor

• Tools Required: MAF cleaner, screwdriver.
• Locate the MAF sensor on the intake manifold.
• Disconnect the sensor's electrical connector.
• Remove the sensor from the intake.
• Clean the sensor with MAF cleaner, avoiding direct contact with the sensor element.

5. Check Fuel Pressure

• Tools Required: Fuel pressure gauge.
