Solution

1. Preparation

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

2. Inspect and Replace Air Filter

Open the air filter housing.
Remove the old air filter and inspect for dirt or blockages.
Install a new air filter (part number as specified in the owner's manual).
Close the air filter housing securely.

3. Clean or Replace Fuel Injectors

Remove the fuel rail (ensure to relieve fuel pressure first).
Clean injectors using a fuel injector cleaning kit or replace if necessary.
Reinstall the fuel rail and ensure all connections are secure.

4. Check and Repair Vacuum Leaks

Inspect all vacuum hoses for cracks or disconnections.
Replace any damaged hoses with new ones.
Use a smoke machine or carburetor cleaner to identify hard-to-find leaks.

5. Test Fuel Pressure

Connect a fuel pressure gauge to the fuel rail.
Turn the ignition to the "ON" position (do not start the engine) and check the pressure reading.
If pressure is below specifications, consider replacing the fuel pump.
