my Honda Accord feels like it's losing power when I accelerate what's wrong

Solution

1. Preparation

• Gather all necessary tools and parts.
• Disconnect the battery to avoid electrical shorts during repairs.
• Allow the engine to cool before starting work.

2. Replace Air Filter

• Remove the air intake cover using a socket set.
• Take out the old air filter and clean the housing.
• Install the new air filter, ensuring it fits snugly.
• Reattach the air intake cover.

3. Fuel Pressure Test and Replacement

• Connect a fuel pressure gauge to the fuel rail.
• Turn the ignition to the "ON" position without starting the engine to check the pressure reading.
• If pressure is low, replace the fuel pump:
  • Drain the fuel tank.
  • Disconnect the battery.
  • Remove the fuel tank from the vehicle.
  • Replace the fuel pump assembly.
  • Reinstall the fuel tank and reconnect all lines.

4. Inspect and Replace Spark Plugs

• Remove the ignition coils or spark plug wires as necessary.
• Use a spark plug socket to remove the old spark plugs.
• Inspect for wear; if worn, replace with new plugs, ensuring correct gap setting.
• Reinstall the spark plugs and reconnect the ignition coils or wires.

5. Check and Replace Vacuum Hoses

• Visually inspect all vacuum hoses for cracks or disconnections.
• Replace any damaged hoses with new ones.
• Ensure all connections are tight and secured.

6. Test and Replace Throttle Position Sensor (if necessary)

• Disconnect the connector from the TPS.
• Use a multimeter to measure the voltage output while moving the throttle.
• If the voltage does not vary smoothly, replace the TPS:
  • Remove the bolts securing the TPS.
  • Install the new TPS and reconnect the wiring.
