why does my Honda Accord have a loss of power during acceleration

Solution

1. Preparation

• Gather tools: OBD-II scanner, fuel pressure gauge, socket set, torque wrench, and basic hand tools.
• Disconnect the negative terminal of the battery for safety.

2. Clean or Replace Air Filter

• Locate the air filter housing (usually near the engine).
• Remove the air filter cover by unscrewing or unclipping it.
• Take out the air filter; inspect for dirt and damage.
  • If dirty, clean or replace the air filter with a new one.
• Reassemble the air filter housing.

3. Clean Throttle Body

• Locate the throttle body (between the air filter and intake manifold).
• Remove the intake duct or hose connected to the throttle body.
• Use throttle body cleaner and a soft brush to clean the inside of the throttle body.
• Ensure the throttle plate moves freely and is not sticking.
• Reattach the intake duct or hose securely.

4. Test and Replace Fuel Filter (if necessary)

• Locate the fuel filter (may be in the fuel line or inside the fuel tank).
• If the fuel pressure test indicated low pressure, remove and replace the fuel filter.
  • Use a wrench to disconnect fuel lines carefully.
  • Install the new fuel filter, ensuring correct orientation and secure connections.

5. Inspect and Replace Spark Plugs and Ignition Coils (if necessary)

• Remove ignition coil connectors and unscrew coils from the engine.
• Remove spark plugs using a spark plug socket.
• Inspect the spark plugs for wear; replace them if worn or fouled.
• Install new spark plugs and torque them to manufacturer specifications (usually around 13-15 lb-ft).
• Reattach ignition coils and connectors.
