Solution

1. Preparation

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

2. Replace Air Filter

Tools Required: Socket set, screwdriver
Sub-steps:
1. Locate the air filter box (typically near the engine).
2. Remove the clips or screws securing the air filter cover.
3. Take out the old air filter and inspect it for dirt and debris.
4. Install a new air filter, ensuring it fits snugly in the housing.
5. Reattach the cover and secure it with clips or screws.

3. Clean or Replace MAF Sensor

Tools Required: MAF cleaner, screwdriver
Sub-steps:
1. Locate the MAF sensor, usually found between the air intake and throttle body.
2. Carefully disconnect the electrical connector.
3. Remove the MAF sensor from its housing using a screwdriver.
4. Spray MAF cleaner onto the sensor element without touching it.
5. Allow it to dry completely before reinstalling it.
6. Reattach the sensor and connector securely.

4. Inspect and Clean Fuel Injectors

Tools Required: Fuel injector cleaner, hand tools
Sub-steps:
1. Remove the fuel rail as per manufacturer’s instructions.
2. Take out each fuel injector and check for clogging.
3. Soak the injectors in a fuel injector cleaner solution.
4. Reinstall clean injectors and ensure they are seated properly in the rail.
5. Reattach the fuel rail to the engine.

5. Tire Pressure Adjustment

Tools Required: Tire pressure gauge, air compressor
Sub-steps:
1. Check each tire's pressure using a tire pressure gauge.
2. Inflate tires to the manufacturer-recommended pressure (found on the driver’s door jamb).
3. Inspect tires for uneven wear and proper alignment.
