Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery before working on any electrical components.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Replace Air Filter

Remove the air filter cover by unscrewing any fasteners or unclipping it.
Take out the old air filter and inspect it for dirt and damage.
Install a new, clean air filter, ensuring it fits snugly in the housing.
Reattach the air filter cover and secure it.

3. Inspect and Clean Fuel Injectors

Use a fuel injector cleaning kit or take the vehicle to a professional for cleaning.
If replacing, use a socket set to disconnect the fuel rail and remove the old injectors.
Install new fuel injectors, ensuring proper seating and securing them according to the manufacturer’s specifications.

4. Check Tire Pressure

Use a tire pressure gauge to measure tire pressure and compare it to the manufacturer's specifications.
Inflate tires to the recommended pressure if low, or replace tires if they are overly worn.

5. Oil Change

Drain the old engine oil using a socket set to remove the oil drain plug.
Replace the oil filter using an oil filter wrench.
Refill with the manufacturer-recommended oil type and quantity, ensuring it meets specifications.
