why does my Toyota Camry lose power when accelerating

Solution

1. Preparation

• Gather tools and parts needed for repair.
• Disconnect the battery to prevent electrical shorts.
• Allow the engine to cool before starting work.

2. Clean or Replace Filter Components

• Air Filter:
  • Remove the air intake duct.
  • Replace or clean the air filter as needed.
• Fuel Filter:
  • Locate the fuel filter (refer to the vehicle's service manual).
  • Disconnect the fuel lines carefully (use safety goggles).
  • Replace the fuel filter with a new one, ensuring proper orientation.

3. Throttle Body Cleaning

• Remove the throttle body assembly from the intake manifold.
• Use throttle body cleaner and a soft brush to clean the inside of the throttle body.
• Ensure the throttle plate moves freely.
• Reinstall the throttle body with new gaskets as necessary, following torque specifications.

4. Ignition System Check

• Remove spark plugs and inspect for wear or carbon buildup.
• Replace spark plugs if they are worn or fouled.
• Test ignition coils using a multimeter to ensure they are functioning within specifications.
• Replace any faulty ignition components.

5. Fuel System Inspection

• Reconnect the fuel pressure gauge and turn the ignition to the "On" position (do not start the engine) to check fuel pressure.
• If pressure is low, inspect the fuel pump and relay for functionality.
• Replace the fuel pump if necessary, following manufacturer guidelines.
