Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to ensure safety during electrical inspections.

2. Inspect and Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the old air filter and check for dirt and blockages.
Install a new air filter that meets OEM specifications.
Reassemble the air filter housing and secure it properly.

3. Clean or Replace Fuel Injectors

Remove the fuel injector rail by detaching the fuel lines and connectors.
Use a fuel injector cleaning kit or replace the injectors with new ones if clogged.
Reinstall the fuel injector rail and ensure all connections are tight.

4. Test and Replace Oxygen Sensors

Locate the upstream and downstream oxygen sensors.
Disconnect the electrical connectors and use a multimeter to test the sensors.
Replace any faulty oxygen sensors with new ones.

5. Check Tire Pressure and Condition

Use a tire pressure gauge to check the air pressure in all tires.
Inflate tires to the recommended pressure as stated on the door jamb sticker.
Inspect the tires for uneven wear or damage and replace if necessary.
