Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, multimeter, cleaning supplies, and safety gear.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Address Error Codes

Clear any error codes found during the diagnostic step.
Reconnect the battery and start the engine to check if the stalling persists.

3. Fuel System Inspection

Tools Needed: Fuel pressure gauge
Remove the fuel pump relay and use the fuel pressure gauge to check the fuel pressure at the rail.
If pressure is low, inspect or replace the fuel filter and fuel pump as necessary.

4. Air Intake System Cleaning

Remove the air intake duct to access the throttle body.
Use throttle body cleaner to remove any carbon buildup from the throttle body.
Reattach the air intake duct securely.

5. Spark Plug and Ignition System Check

Remove the spark plugs using a socket set.
Inspect each spark plug for wear or fouling and replace if necessary.
Test ignition coils with a multimeter to ensure they are functioning within specifications.

6. Test Drive

After all repairs, reconnect the negative battery terminal.
Take the vehicle for a test drive to ensure the stalling issue has been resolved.
