why does my Toyota RAV4 have poor acceleration

Solution

1. Preparation

• Gather tools and parts required for the repair.
• Ensure the vehicle is parked on a level surface and engage the parking brake.
• 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 old air filter and inspect for dirt or damage.
• If necessary, install a new air filter, ensuring it fits snugly in the housing.
• Reattach the air filter housing cover and secure it.

3. Inspect and Clean Throttle Body

• Remove the intake duct connected to the throttle body using a socket set.
• Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding areas.
• Reattach the intake duct securely to prevent air leaks.

4. Test and Replace Spark Plugs

• Remove the ignition coil or spark plug wires using a socket set.
• Inspect spark plugs for wear or fouling; replace if necessary with OEM parts.
• Reinstall ignition coils or spark plug wires ensuring a secure connection.

5. Check Fuel Pressure

• Connect a fuel pressure gauge to the fuel rail test port.
• Start the engine and observe the pressure reading; it should match manufacturer specifications.
• If pressure is low, consider replacing the fuel pump or filter as needed.
