why is my Toyota RAV4 XA40 (2013-2018) stalling at red lights

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the battery to ensure safety while working on electrical components.
• Allow the engine to cool down before starting any work.

2. Clean the Throttle Body

• Remove the air intake duct to access the throttle body.
• Use throttle body cleaner and a soft cloth to clean the inside of the throttle body, ensuring no carbon buildup is present.
• Reinstall the air intake duct securely.

3. Inspect and Replace Spark Plugs

• Remove the engine cover if applicable to access the spark plugs.
• Use a spark plug socket to remove the old spark plugs.
• Inspect the old plugs for wear and replace them with new ones, ensuring the correct gap and torque specifications (typically around 13 lb-ft).
• Reinstall the engine cover.

4. Test and Clean the Idle Air Control Valve (IAC)

• Locate the IAC valve (usually near the throttle body).
• Disconnect the electrical connector and remove the IAC valve using the appropriate socket.
• Clean the valve with throttle body cleaner and inspect for damage.
• Reinstall the IAC valve and reconnect the electrical connector.

5. Check for Vacuum Leaks

• Inspect all vacuum hoses connected to the intake manifold for cracks or disconnections.
• Replace any damaged hoses.
• Perform a smoke test if necessary to identify hard-to-find leaks.
