why does my Honda Accord keep stalling at red lights

Solution

1. Preparation

• Gather tools and parts needed for the repair. Ensure the vehicle is parked on a level surface and the engine is turned off.
• Tools Required: OBD-II scanner, socket set, fuel pressure gauge, throttle body cleaner, multimeter.

2. Clean the Throttle Body

• Disconnect the negative battery terminal to prevent electrical shorts.
• Remove the air intake duct connected to the throttle body.
• Use throttle body cleaner and a soft cloth to clean the interior surfaces of the throttle body.
• Reinstall the air intake duct and reconnect the battery terminal.

3. Replace Fuel Filter (if applicable)

• Locate the fuel filter in the fuel line; it may require removal of a panel or cover.
• Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
• Disconnect the fuel lines from the filter (be cautious of residual fuel).
• Install the new fuel filter, ensuring proper orientation and connection.
• Reinstall any panels or covers and reconnect the fuel pump fuse.

4. Check and Replace Spark Plugs (if needed)

• Remove the ignition coil cover (if applicable) and disconnect the ignition coils.
• Remove the spark plugs using a socket and extension, inspecting for wear or fouling.
• Replace with new spark plugs (ensure correct gap and type as specified by the manufacturer).
• Reinstall the ignition coils and cover.
