Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface.
Disconnect the battery to prevent electrical shorts when working on the fuel system.

2. Fuel Injector Cleaning

Remove the fuel rail from the engine by unscrewing the mounting bolts.
Disconnect the fuel lines from the fuel injectors using a wrench.
Use a fuel injector cleaning kit to flush the injectors.
- Follow the instructions specific to the cleaning kit used.
Reassemble the fuel rail with the cleaned injectors, ensuring proper orientation and sealing.

3. Replace Air Filter

Locate the air filter housing, usually at the engine's intake.
Remove the clips or screws securing the housing.
Take out the old air filter and inspect the housing for dirt.
Place the new air filter into the housing, ensuring it fits snugly.
Reassemble the air filter housing and secure it.

4. Vacuum Leak Repair

Inspect all vacuum hoses connected to the intake manifold for cracks or disconnections.
Replace any damaged hoses with new ones of the same diameter and length.
Tighten all connections to ensure a proper seal.

5. Tire Maintenance

Check the tire pressure using a tire pressure gauge.
Inflate tires to the manufacturer-recommended PSI, usually found on a sticker inside the driver’s door frame.
Inspect tires for uneven wear and consider rotating or aligning them if necessary.
