Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, fuel pressure gauge, screwdrivers.
Disconnect the battery to ensure safety while working on electrical components.
Allow the engine to cool down before any inspection.

2. Inspect Fuel System

Sub-steps:
1. Remove the fuel pump fuse/relay to relieve fuel pressure.
2. Disconnect the fuel lines using appropriate wrenches.
3. Check the fuel filter for clogs and replace if necessary.
4. Test the fuel pump using a fuel pressure gauge; it should read within manufacturer specifications (typically around 40-50 psi).
5. Replace the fuel pump if the pressure is below specifications.

3. Check Ignition System

Sub-steps:
1. Remove the engine cover if applicable to access ignition components.
2. Inspect spark plugs for wear or carbon buildup; replace if needed.
3. Use a multimeter to test ignition coils; ensure they meet resistance specifications.
4. Replace any faulty ignition coils.

4. Clean Throttle Body and Air Intake

Sub-steps:
1. Disconnect the air intake hose from the throttle body.
2. Use throttle body cleaner and a soft brush to clean the throttle body and idle air control valve.
3. Reattach the air intake hose securely.

5. Reconnect and Test

Sub-steps:
1. Reconnect the battery.
2. Start the engine and let it idle; check for smooth operation.
3. Take the vehicle for a test drive to ensure that it no longer stalls.
