Solution

1. Preparation

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

2. Clean or Replace Air Filter

Remove the air filter housing cover using a socket set.
Inspect the air filter; if dirty, replace it with a new one.
Reinstall the housing cover securely.

3. Throttle Body Cleaning

Locate the throttle body and remove the intake duct by loosening the clamps.
Spray throttle body cleaner on a clean cloth and wipe the throttle plate and surrounding areas.
Reassemble the intake duct and secure it with clamps.

4. Fuel Pressure Check

Attach the fuel pressure gauge to the fuel rail's Schrader valve.
Turn the ignition to the "ON" position without starting the engine to check the pressure reading.
If the pressure is below specifications, consider replacing the fuel pump or fuel filter.

5. Inspect Ignition System

Remove the spark plugs using a spark plug socket.
Check the condition of the spark plugs; replace them if they show signs of wear.
Test the ignition coils with a multimeter to ensure they are functioning correctly; replace any faulty coils.

6. Check for Vacuum Leaks

Visually inspect all vacuum hoses connected to the intake manifold for cracks or disconnections.
Use a smoke machine or carburetor cleaner to identify leaks while the engine is running.
Replace any damaged hoses as necessary.
