Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical short circuits.

2. Inspect Fuel System

Sub-steps:
1. Remove the fuel pump relay from the fuse box.
2. Disconnect the fuel line from the fuel rail (use a rag to catch any fuel).
3. Attach a fuel pressure gauge to the fuel rail.
4. Reconnect the fuel pump relay and turn the ignition key to the "On" position (do not start the engine) to check for proper fuel pressure.
Tools Required: Fuel pressure gauge, socket set
Safety Warnings: Fuel is flammable; work in a well-ventilated area away from sparks or open flames.

3. Clean Throttle Body

Sub-steps:
1. Remove the air intake duct to access the throttle body.
2. Use throttle body cleaner and a soft cloth to clean the inside of the throttle body.
3. Ensure the throttle plate moves freely and is not sticking.
4. Reinstall the air intake duct securely.
Tools Required: Throttle body cleaner, soft cloth
Safety Warnings: Allow the engine to cool before working on the intake system.

4. Replace Spark Plugs (if necessary)

Sub-steps:
1. Remove the ignition coils by disconnecting the electrical connectors and unscrewing the bolts.
2. Extract the old spark plugs using a spark plug socket.
3. Check the spark plug condition; replace if fouled or worn.
4. Install new spark plugs to the manufacturer’s torque specifications (typically around 13-15 lb-ft).
5. Reinstall the ignition coils.
Tools Required: Spark plug socket, torque wrench
Safety Warnings: Disconnect battery before servicing electrical components.
