1. Preparation

Gather necessary tools and parts.
Ensure vehicle is on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety during electrical inspections.

2. Replace Air Filter

Locate the air filter housing.
Remove the clips or screws securing the housing.
Take out the old air filter and inspect for dirt and debris.
Install a new air filter according to the manufacturer’s specifications.
Re-secure the air filter housing.

3. Clean or Replace Fuel Injectors

If injectors are clogged, use an appropriate fuel injector cleaning kit.
Disconnect the fuel lines from the injectors.
Remove the fuel rail and injectors from the engine.
Clean the injectors with a cleaning solution or replace them if damaged.
Reassemble the fuel rail and ensure all connections are secure.

4. Check Tire Pressure

Use a tire pressure gauge to check the pressure of all tires.
Inflate or deflate tires to the manufacturer-recommended pressures.
Inspect tires for uneven wear and replace if necessary.
