Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery before working on any electrical components.

2. Replace Air Filter

Locate the air filter housing, typically found at the front of the engine bay.
Remove the screws or clips securing the housing.
Take out the old air filter and clean the housing interior.
Install a new air filter, ensuring it fits snugly.
Re-secure the housing with screws or clips.

3. Clean or Replace Fuel Injectors

Remove the engine cover to access the fuel rail.
Disconnect the fuel lines using a line wrench, taking care to catch any fuel in a suitable container.
Remove the fuel injectors from the rail by releasing the clips and pulling them out.
Clean the injectors using a specialized cleaning kit or replace them if they are damaged.
Reinstall the injectors and reconnect the fuel lines.

4. Check Tire Pressure and Condition

Use a tire pressure gauge to check the pressure of all tires, including the spare.
Inflate tires to the recommended pressure as indicated in the owner’s manual or on the door jamb sticker.
Inspect tires for uneven wear or damage; replace if necessary.

5. Change Engine Oil

Raise the vehicle using a jack and secure it on jack stands.
Remove the oil drain plug using a socket set and allow the oil to drain into a container.
Replace the oil filter using an oil filter wrench.
Reinstall the drain plug and refill the engine with the recommended oil type.
