1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Replace Air Filter

Locate the air filter housing.
Open the housing by releasing the clips or screws.
Remove the old air filter and inspect the housing for debris.
Insert the new air filter, ensuring it is properly seated.
Reassemble the housing and secure it.

3. Clean or Replace Fuel Injectors

Remove the fuel injector rail by disconnecting the fuel lines and bolts.
Carefully remove the injectors from the rail.
Either clean the injectors using a fuel injector cleaning kit or replace them with new ones.
Reinstall the injectors onto the rail and reconnect the fuel line securely.

4. Check and Adjust Tire Pressure

Use a tire pressure gauge to check each tire's pressure.
Inflate tires to the recommended PSI as indicated on the driver’s door jamb.
Inspect tires for excessive wear and replace if necessary.

5. Change Engine Oil

Drain the old engine oil using a socket set to remove the oil drain plug.
Replace the oil filter with a new one.
Refill the engine with the manufacturer-recommended oil type and quantity.
