Solution

1. Preparation

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

2. Replace the Air Filter

• Remove the air filter cover using a socket set.
• Take out the old air filter and inspect it for dirt and damage.
• Install a new air filter, ensuring it is seated properly.

3. Clean or Replace Fuel Injectors

• If injectors are clogged, use a fuel injector cleaning kit or remove them for ultrasonic cleaning.
• If damaged, replace the fuel injectors with OEM parts.
• Reinstall injectors and ensure all connections are secure.

4. Check and Adjust Tire Pressure
