Solution

1. Preparation

Tools Required: OBD-II scanner, fuel pressure gauge, socket set, multimeter, general hand tools.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent any electrical shorts during repairs.

2. Clean or Replace Air Filter

Sub-steps:
1. Locate the air filter housing and remove the clips or screws.
2. Take out the air filter and inspect it for dirt and debris.
3. If dirty, clean it with compressed air or replace it with a new filter.
Safety Warning: Ensure the engine is off to avoid accidental operation during inspection.

3. Inspect and Clean MAF Sensor

Sub-steps:
1. Locate the MAF sensor in the air intake system.
2. Disconnect the electrical connector from the MAF sensor.
3. Remove the MAF sensor with a suitable socket.
4. Clean the sensor with MAF cleaner spray and let it dry completely before reinstallation.
Tools Required: MAF cleaner, socket set.

4. Check and Clean Fuel Injectors

Sub-steps:
1. Remove the engine cover if necessary to access the fuel rail.
2. Disconnect the fuel lines and electrical connectors from the fuel injectors.
3. Remove the injectors from the fuel rail and inspect for dirt or leaks.
4. Use a fuel injector cleaning kit or replace them if heavily clogged.
Tools Required: Fuel injector cleaning kit, socket set.

5. Tire Pressure Adjustment

Sub-steps:
1. Check tire pressure using a tire pressure gauge.
2. Inflate or deflate tires to the manufacturer's recommended pressure.
Safety Warning: Ensure the vehicle is on a level surface while checking tire pressure.
