Solution

1. Preparation

Tools Required: OBD-II scanner, fuel pressure gauge, socket set, torque wrench, multimeter, cleaning supplies.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical shorts during repairs.

2. Inspect and Clean Throttle Body

Remove the air intake duct connected to the throttle body.
Sub-steps:
1. Use a throttle body cleaner and a soft cloth to clean the throttle body.
2. Ensure the throttle plate moves freely and is not stuck.
3. Reattach the air intake duct and secure it with the appropriate fasteners.

3. Test and Repair Fuel System

Attach the fuel pressure gauge to the fuel rail.
Sub-steps:
1. Turn the ignition to the "ON" position without starting the engine and check for proper fuel pressure.
2. If the pressure is low, inspect the fuel pump and replace it if necessary.
3. Check fuel filter for clogs and replace it if needed.
4. Reconnect the fuel line and ensure there are no leaks.

4. Check Ignition System

Remove the spark plugs for inspection.
Sub-steps:
1. Inspect spark plugs for wear and carbon buildup; replace if necessary.
2. Test ignition coils with a multimeter for proper resistance; replace any faulty coils.
3. Reinstall the spark plugs and secure them to the proper torque specification.

5. Reconnect Battery and Test

Reconnect the battery terminals, ensuring they are secure.
Start the engine and monitor for any unusual noises or warning lights.
