why is my Toyota Tacoma N300 (2016-Present) using so much fuel lately

Solution

1. Preparation

• Gather tools and parts needed for the repair.
• Disconnect the negative terminal of the battery to ensure safety.

2. Inspect and Replace Air Filter

• Remove the air filter housing cover by unscrewing any fasteners (usually Phillips or Torx screws).
• Take out the old air filter and inspect for dirt or damage.
• Install a new air filter (ensure it is the correct part for your model).
• Reattach the air filter housing cover and secure it.

3. Test and Clean Fuel Injectors

• Disconnect the fuel injector connectors and remove the injectors using a socket wrench.
• Clean the injectors using a professional fuel injector cleaning kit or replace them if necessary.
• Reinstall the fuel injectors and reconnect the connectors.

4. Replace Spark Plugs

• Remove the ignition coils (if applicable) to access the spark plugs.
• Using a spark plug socket, unscrew and remove the old spark plugs.
• Check the gap on new spark plugs and install them according to the manufacturer's specifications.
• Reinstall the ignition coils and ensure they are connected properly.

5. Tire Pressure Check

• Use a tire pressure gauge to measure the tire pressure on all four tires.
• Inflate tires to the manufacturer’s recommended PSI (found in the owner’s manual or on the door jamb).
• Inspect the tires for uneven wear and replace if necessary.
