Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shock.

2. Fuel System Inspection

Tools Required: Fuel pressure gauge, socket set
Steps:
1. Locate the fuel pump fuse in the fuse box and remove it.
2. Connect the fuel pressure gauge to the fuel rail test port.
3. Reinsert the fuel pump fuse and turn the ignition to the ON position (do not start the engine) to check pressure. It should be within the manufacturer’s specifications.
4. If pressure is low, replace the fuel filter or fuel pump as necessary.

3. Air Intake System Check

Tools Required: Screwdriver set, vacuum gauge
Steps:
1. Remove the air intake duct and inspect for any obstructions or damage.
2. Check the air filter for dirt and replace if necessary.
3. Use a vacuum gauge to check for vacuum leaks; if the reading is low, inspect hoses connected to the intake manifold for cracks or disconnections.

4. Ignition System Inspection

Tools Required: Spark plug socket, multimeter
Steps:
1. Remove the spark plugs and inspect for wear or fouling.
2. Test the ignition coils with a multimeter for proper resistance according to specifications.
3. Replace any faulty spark plugs or ignition coils.

5. Reassemble and Reconnect

Reinstall all components in reverse order of removal.
Reconnect the negative battery terminal.
Clear any stored trouble codes using the OBD-II scanner.
