my Toyota RAV4 XA40 (2013-2018) has poor acceleration, what could be wrong

Solution

1. Preparation

• Gather all necessary tools and parts.
• Ensure the vehicle is parked on a flat surface and the engine is off.
• Disconnect the battery before starting work to prevent electrical shorts.

2. Clean or Replace Air Filter

• Remove the air filter cover using a socket set.
• Inspect the air filter for dirt and debris.
• If dirty, clean it with compressed air or replace it with a new part (ensure it meets OEM specifications).

3. Fuel System Inspection

• Connect the fuel pressure gauge to the fuel rail.
• Turn the ignition to the ON position (do not start the engine) and check the pressure.
• If the pressure is below specifications (typically around 30-50 psi for most RAV4s), replace the fuel pump or filter as necessary.

4. Throttle Body Cleaning

• Remove the throttle body using a socket set (ensure to label any connectors).
• Clean the throttle body with throttle body cleaner and a soft cloth to remove carbon buildup.
• Reinstall the throttle body and reconnect all components securely.

5. Spark Plug Replacement

• Remove the spark plug wires or ignition coils (as applicable).
• Use a spark plug socket to remove the old spark plugs.
• Inspect and replace with new spark plugs that match OEM specifications (typically NGK or Denso).
• Reinstall ignition coils or spark plug wires.

6. Exhaust System Check

• Inspect the exhaust for any visible blockages or damage.
• Use a smoke test if necessary to identify leaks.
• Repair or replace damaged sections of the exhaust system.
