what causes my Toyota Camry to lose power when accelerating

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a flat surface and the engine is cool.
• Disconnect the battery to prevent electrical shock.

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 and debris.
• Clean the filter if reusable or replace it with a new one if excessively dirty.

3. Test and Replace Fuel Pump (if necessary)

• Connect a fuel pressure gauge to the fuel rail.
• Turn the ignition on (without starting the engine) to check pressure.
• If pressure is below specifications, replace the fuel pump:
  • Relieve fuel pressure by removing the fuel pump fuse and running the engine until it stalls.
  • Disconnect the battery and remove the fuel tank as per the service manual.
  • Replace the fuel pump and reassemble the components, ensuring all connections are secure.

4. Clean Throttle Body

• Remove the intake duct connected to the throttle body using a socket set.
• Use throttle body cleaner and a soft brush to remove carbon deposits from the throttle body.
• Reassemble the intake duct and reconnect the battery.

5. Inspect and Replace Ignition Components

• Remove the spark plugs using a spark plug socket.
• Check for signs of wear or carbon buildup.
• Replace spark plugs if necessary and inspect ignition coils for damage.
• Reinstall spark plugs and reconnect ignition coils.

6. Fix Vacuum Leaks

• Visually inspect vacuum lines for cracks or disconnections.
• Replace any damaged vacuum hoses and ensure all connections are tight.
