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 shock.

2. Inspect the Battery

Sub-steps:
- Use a multimeter to check battery voltage; it should be at least 12.6 volts.
- Clean battery terminals with a wire brush if corrosion is present.
- Tighten any loose connections.

3. Fuel System Check

Sub-steps:
- Connect a fuel pressure gauge to the fuel rail.
- Turn the ignition to the "ON" position (do not start) and check the fuel pressure; it should typically be around 50-60 psi.
- If low, inspect the fuel pump and fuel filter for blockage or failures.

4. Air Intake Inspection

Sub-steps:
- Remove the air intake duct and inspect for any obstructions or damage.
- Check the air filter; replace if dirty.
- Ensure that all hoses and connections are secure and free of leaks.

5. Spark Plug and Ignition Coil Check

Sub-steps:
- Remove the spark plugs using a spark plug socket and inspect for wear or carbon buildup.
- Replace spark plugs if worn or fouled, using OEM parts with the correct gap.
- Test the ignition coils using a multimeter; replace any faulty coils.

6. Reassemble and Test

Sub-steps:
- Reinstall any components that were removed during inspection.
- Reconnect the battery.
- Start the engine and monitor for rough idle or stalling.
