why does my Toyota RAV4 Fifth Generation (2019-present) engine stall when idling

Solution

1. Preparation

• Gather tools and parts. Ensure the vehicle is parked on a level surface and the engine is cool.
• Tools Required: OBD-II scanner, fuel pressure gauge, socket set, screwdrivers, cleaning supplies (e.g., throttle body cleaner).
• Safety Warnings: Disconnect the battery before working on electrical components.

2. Clean the Throttle Body

• Remove the intake duct connected to the throttle body using a socket set.
• Spray throttle body cleaner onto a clean cloth and wipe the inside of the throttle body until clean.
• Reinstall the intake duct and ensure it is securely fastened.

3. Inspect and Replace Air Filter

• Open the air filter housing by removing the clips or screws.
• Take out the existing air filter and inspect it for dirt and damage.
• Replace with a new air filter if necessary, ensuring it fits snugly in the housing.

4. Test and Repair Fuel System

• Connect the fuel pressure gauge to the fuel rail test port.
• Turn the ignition key to the "On" position (do not start the engine) and check the pressure reading against manufacturer specifications.
• If fuel pressure is low, check the fuel pump and fuel filter for issues. Replace any defective components.

5. Check for Vacuum Leaks

• Inspect all vacuum hoses for cracks or disconnections.
• Replace any damaged hoses and ensure all connections are tight.
