Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Fuel System Inspection

Tools Required: Fuel pressure gauge, safety glasses, rags
Sub-steps:
1. Locate the fuel pressure test port on the fuel rail.
2. Attach the fuel pressure gauge to the test port.
3. Turn the ignition to the "ON" position (do not start the engine) and check the pressure reading against manufacturer specifications.
4. If pressure is low, inspect the fuel pump and fuel filter for clogs or failures.
5. If necessary, replace the fuel filter and/or fuel pump.

3. Air Intake System Examination

Tools Required: Socket set, screwdrivers
Sub-steps:
1. Remove the air intake duct and inspect for any obstructions or damage.
2. Clean the air filter or replace it if it is dirty.
3. Check the mass airflow sensor (MAF) for dirt or damage and clean it if necessary.

4. Ignition System Check

Tools Required: Spark plug socket, torque wrench
Sub-steps:
1. Remove the spark plugs using the spark plug socket.
2. Inspect the spark plugs for wear; replace them if they show signs of fouling or excessive wear.
3. Test the ignition coils with a multimeter to ensure they are functioning properly.
4. Replace any faulty ignition coils.

5. Reconnect and Test

Reconnect the battery.
Start the engine and allow it to idle while monitoring for any irregularities.
