how to stop my Honda CR-V from stalling when I come to a stop

Solution

1. Preparation

• Gather tools: OBD-II scanner, socket set, multimeter, cleaning supplies, and safety goggles.
• Ensure the vehicle is parked on a level surface and the engine is cool.

2. Clean the Throttle Body

• Tools Required: Throttle body cleaner, soft cloth.
• Disconnect the negative battery terminal to prevent electrical shock.
• Remove the air intake duct to access the throttle body.
• Spray throttle body cleaner onto a soft cloth and wipe the throttle body, focusing on the inner walls and plate.
• Reinstall the air intake duct and reconnect the battery.

3. Inspect and Clean the IAC Valve

• Tools Required: Socket set, cleaning supplies.
• Locate the IAC valve on the intake manifold.
• Remove the IAC valve from its mounting position.
• Clean the valve with throttle body cleaner; ensure the passage is unobstructed.
• Reinstall the IAC valve securely.

4. Check the Fuel System

• Tools Required: Fuel pressure gauge.
• Locate the fuel pressure test port on the fuel rail.
• Connect the fuel pressure gauge and turn the ignition to the "ON" position (do not start the engine).
• Record the fuel pressure reading; compare it to manufacturer specifications.
• If the pressure is low, inspect the fuel pump and replace if necessary.

5. Inspect the MAF Sensor

• Tools Required: Torx screwdriver or socket set.
• Disconnect the electrical connector from the MAF sensor.
• Remove the MAF sensor from the air intake duct.
• Inspect for dirt or debris; clean the sensor gently with MAF cleaner.
• Reinstall the MAF sensor and reconnect the electrical connector.
