Solution

1. Preparation

Gather tools and parts required.
Disconnect the battery to ensure safety while performing repairs.
Ensure the vehicle is on a flat surface and secure with wheel chocks.

2. Inspect and Replace Spark Plugs

Remove the ignition coils using a socket set.
Pull out the spark plugs using a spark plug socket.
Inspect spark plugs for wear; replace with OEM or equivalent spark plugs if necessary (torque to manufacturer's specifications).
Reinstall ignition coils.

3. Clean Throttle Body

Locate the throttle body and remove the intake ducting.
Use throttle body cleaner and a soft cloth to clean the interior of the throttle body.
Be cautious not to damage the throttle position sensor.
Reassemble the intake ducting securely.

4. Fuel System Check

Attach a fuel pressure gauge to the fuel rail.
Start the engine and check that fuel pressure is within the manufacturer’s specified range.
If pressure is low, consider replacing the fuel filter or fuel pump.
Disconnect the fuel gauge and reattach the fuel rail cover.

5. Vacuum Leak Inspection

Visually inspect all vacuum lines for cracks or disconnections.
Use a smoke machine or carburetor cleaner around the vacuum lines while the engine is running to identify leaks.
Replace any damaged lines as needed.
