why does my Toyota RAV4 have poor fuel economy lately

Solution

1. Preparation

• Gather tools and parts needed for repairs.
• Park the vehicle on a flat surface and ensure the engine is cool.
• Disconnect the negative battery terminal to avoid electrical issues.

2. Replace Air Filter

• Remove the air filter housing cover using a socket set.
• Take out the old air filter and inspect it for dirt and debris.
• Install a new air filter, ensuring it is seated properly.
• Reattach the housing cover and tighten it securely.

3. Clean Fuel Injectors

• Use a fuel injector cleaning kit or a high-quality fuel injector cleaner.
• Follow the manufacturer’s instructions for the cleaning process.
• If necessary, remove the injectors from the engine using appropriate socket sizes.
• Clean each injector with a specialized cleaning solution and reinstall them.

4. Replace Fuel Filter

• Locate the fuel filter, typically found along the fuel line.
• Use a wrench to carefully disconnect the fuel lines from the filter, taking care to avoid fuel spillage.
• Replace the old filter with a new one, ensuring the direction of flow is correct.
• Reconnect the fuel lines securely and check for leaks.

5. Check Tire Pressure

• Use a tire pressure gauge to check each tire's pressure.
• Inflate tires to the recommended PSI as indicated on the driver’s side door jamb.
• Inspect tires for uneven wear, which may indicate alignment issues.
