my Honda Accord stalls when I come to a stop what could be wrong

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the battery to prevent any electrical issues during the repair.

2. Clean the Throttle Body

• Remove the air intake duct connected to the throttle body.
• Use throttle body cleaner and a soft cloth to clean the inside of the throttle body.
• Ensure that the throttle plate moves freely and is not sticking.
• Reattach the air intake duct securely.

3. Inspect and Clean the IAC Valve

• Locate the IAC valve, typically near the throttle body.
• Disconnect the electrical connector and remove the mounting screws.
• Clean the valve with throttle body cleaner; ensure the pintle moves freely.
• Reinstall the IAC valve and reconnect the electrical connector.

4. Test and Adjust Fuel Pressure

• Connect the fuel pressure gauge to the fuel rail.
• Start the engine and observe the fuel pressure reading; it should be within the manufacturer’s specifications.
• If pressure is low, check the fuel filter and pump for clogs or failures.
• Replace the fuel filter or pump if necessary.

5. Inspect Vacuum Lines

• Visually inspect all vacuum lines for cracks or disconnections.
• Replace any damaged vacuum lines to ensure proper air intake.
