4
Examine fuel injectors for leaks or clogging.
5
Test the fuel pressure using a fuel pressure gauge to ensure the fuel pump is functioning properly.
6
Inspect the throttle body for carbon buildup or obstructions.
7
Evaluate the engine oil level and condition; excessive oil consumption can affect efficiency.

Solution

1. Preparation

Gather tools and parts needed for repairs.
Disconnect the battery before beginning any work on the vehicle.

2. Replace Air Filter

Remove the air filter housing cover using a screwdriver.
Take out the old air filter.
Install the new air filter, ensuring it fits securely.
Reattach the air filter housing cover and tighten screws.

3. Inspect and Clean Fuel Injectors

Remove the fuel rail by disconnecting the fuel lines (use caution as fuel may spill).
Take out the fuel injectors from the rail.
Clean the injectors using a fuel injector cleaning kit or professional service.
Reinstall the injectors and secure the fuel rail back in place.

4. Clean Throttle Body

Remove the intake duct connected to the throttle body.
Use throttle body cleaner and a soft cloth to clean the interior of the throttle body.
Ensure the throttle plate and surrounding areas are free from carbon buildup.
Reattach the intake duct securely.

5. Check and Adjust Tire Pressure

Use a tire pressure gauge to check each tire.
Inflate tires to the recommended PSI indicated on the door jamb or owner’s manual.
Inspect for any visible damage or uneven wear on tires.
