Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical issues during repairs.

2. Replace Air Filter

Remove the air filter housing cover by unscrewing the retaining screws.
Take out the old air filter and inspect the filter housing for debris.
Install a new, clean air filter ensuring it fits snugly in the housing.
Reattach the air filter housing cover and tighten the screws.

3. Inspect and Clean Fuel Injectors

Remove the fuel injector rail by disconnecting the fuel lines (ensure to relieve fuel pressure first).
Clean the fuel injectors using a specialized injector cleaning solvent or replace them if damaged.
Reinstall the fuel injector rail and reconnect the fuel lines securely.

4. Check for Vacuum Leaks

Inspect all vacuum hoses and connections for cracks or disconnections.
Replace any damaged hoses.
Use a smoke machine to detect hard-to-find leaks, if necessary.

5. Monitor and Adjust Tire Pressure

Use a tire pressure gauge to check each tire’s pressure.
Inflate tires to the manufacturer's recommended PSI levels.
Inspect tires for uneven wear or damage and replace if necessary.
