Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical shorts.

2. Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the old air filter and inspect the housing for debris.
Install the new air filter, ensuring it fits snugly.
Reattach the air filter housing cover and tighten screws to manufacturer specifications.

3. Clean or Replace Fuel Injectors

Remove the fuel rail assembly by disconnecting the fuel lines and electrical connectors.
Use a fuel injector cleaning kit to clean the injectors, or replace them if they are damaged.
Reassemble the fuel rail, ensuring all O-rings are seated properly to avoid leaks.

4. Check and Adjust Tire Pressure

Use a tire pressure gauge to check each tire's pressure.
Inflate tires to the manufacturer-recommended pressure as listed on the driver's door jamb.
Inspect tires for uneven wear patterns and replace if necessary.

5. Inspect Exhaust System

Visually inspect the exhaust for any visible holes or rust.
Use a smoke test to find leaks if necessary.
Replace any damaged exhaust components to ensure proper flow.
