why does my Honda Civic feel like it’s losing power when I accelerate

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 ensure safety while working on electrical components.

2. Clean or Replace Air Filter

• Remove the air filter housing cover using a socket set.
• Take out the air filter and inspect it for dirt or damage.
  • Tools Required: Socket set, screwdriver
• If dirty, clean it with compressed air or replace it with a new one.

3. Inspect and Clean Throttle Body

• Remove the throttle body from the intake manifold.
  • Tools Required: Socket set, torque wrench
• Use throttle body cleaner and a soft cloth to clean the inside surfaces.
• Reinstall the throttle body using the specified torque values (check service manual for exact values).

4. Check and Replace Spark Plugs

• Remove the ignition coil to access the spark plugs.
  • Tools Required: Spark plug socket, ratchet
• Examine each spark plug for wear or carbon buildup; replace if necessary with OEM parts.
• Reinstall the ignition coils after ensuring they are clean and functioning.

5. Perform Fuel Pressure Test

• Connect the fuel pressure gauge to the fuel rail's test port.
• Start the engine and observe the fuel pressure reading; it should match the specifications in the service manual.
• If low, inspect the fuel pump, fuel filter, and fuel lines for blockages or failures.
