my Honda Accord feels like it’s losing power when I drive, what’s wrong

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Spark Plugs

• Remove the ignition coils using a socket set.
• Unscrew and extract the old spark plugs using a spark plug socket.
• Inspect the spark plugs for wear; replace if worn or fouled.
• Install new spark plugs and torque to the manufacturer's specifications (typically 13-15 ft-lbs).

3. Fuel System Inspection

• Connect the fuel pressure gauge to the fuel rail.
• Start the engine and check the pressure reading against manufacturer specifications (usually around 40-50 psi).
• If the pressure is low, inspect the fuel pump and filter for proper operation.
• Replace the fuel filter if clogged or dirty.

4. Throttle Body Cleaning

• Remove the air intake duct to access the throttle body.
• Use throttle body cleaner and a clean cloth to remove carbon buildup on the throttle body plate.
• Reassemble the air intake duct and reconnect any sensors that were removed.

5. Vacuum Leak Check

• Visually inspect all vacuum lines and hoses for cracks or disconnections.
• Use a smoke machine or carburetor cleaner to detect leaks while the engine is running.
