Solution

1. Preparation

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

2. Replace Air Filter

Remove the air filter housing cover using a screwdriver.
Take out the old air filter and inspect the housing for debris.
Install a new air filter, ensuring it fits snugly.
Reattach the air filter housing cover securely.

3. Clean Fuel Injectors

Use a fuel injector cleaning kit or remove the injectors for manual cleaning.
If using a kit, follow the manufacturer's instructions to connect it to the fuel rail.
For manual cleaning, remove the injectors using a socket set, clean them with a specialized cleaning solvent, and then reinstall them.
Ensure proper torque specifications are followed when reinstalling.

4. Inspect and Repair Exhaust System

Visually inspect the exhaust system for holes or rusted areas.
Use a wrench to tighten any loose connections.
Replace any damaged sections of the exhaust with appropriate OEM parts.

5. Check and Adjust Tire Pressure

Use a tire pressure gauge to check the pressure of all tires.
Inflate or deflate tires to match the manufacturer’s recommended specifications found in the owner’s manual.
Inspect tire tread for wear and replace if necessary.
