why does my Toyota RAV4 have poor acceleration after maintenance

Solution

1. Preparation

• Gather tools and parts required.
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the negative battery terminal to prevent any electrical shorts.

2. Inspect and Clean the Throttle Body

• Remove the air intake duct to access the throttle body.
• Use a throttle body cleaner and a soft cloth to clean the inside of the throttle body.
• Ensure the throttle plate opens and closes smoothly.

3. Check and Adjust the Fuel System

• Reconnect the fuel pressure gauge to the fuel rail.
• Start the engine and monitor fuel pressure; it should match manufacturer specifications (typically between 30-50 psi).
• If pressure is low, check the fuel filter and fuel pump for proper operation.

4. Inspect the Air Intake System

• Check for any loose or disconnected hoses in the air intake system.
• Ensure the air filter is clean and properly seated.
• Replace the air filter if it is dirty.

5. Reassemble and Test

• Reconnect all components removed during inspection.
• Ensure the negative battery terminal is reconnected.
• Start the engine and perform a test drive to evaluate acceleration improvement.
