my Honda CR-V stalls when coming to a stop what could be wrong

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the battery to ensure safety during repairs.
• Allow the engine to cool down before starting work.

2. Clean Throttle Body

• Remove the air intake duct connected to the throttle body.
• Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding area.
• Reattach the air intake duct securely.

3. Inspect and Clean IAC Valve

• Remove the IAC valve from the intake manifold.
• Clean the IAC valve using an appropriate cleaner to remove carbon deposits.
• Reinstall the IAC valve, ensuring proper torque specifications are followed (typically around 80-100 in-lbs).

4. Test and Adjust Fuel Pressure

• Attach a fuel pressure gauge to the fuel rail.
• Turn the ignition to the "ON" position (do not start the engine) and check the fuel pressure; it should meet manufacturer specifications (usually around 30-40 psi).
• If pressure is low, inspect the fuel pump and filter; replace if necessary.

5. Inspect Vacuum Hoses

• Visually inspect all vacuum hoses for cracks, breaks, or disconnections.
• Replace any damaged hoses and ensure all connections are secure.

6. Electrical System Check

• Test the battery voltage; it should be above 12.4 volts.
• Inspect the alternator and charging system for proper operation.
• Replace the battery or alternator if any issues are detected.
