Solution

1. Preparation

Tools Required: OBD-II scanner, fuel pressure gauge, multimeter, socket set, torque wrench, basic hand tools.
Disconnect the negative battery terminal to ensure safety during the repair.

2. Address Fuel System Issues

Check Fuel Pump:
1. Remove the access panel to the fuel pump (if applicable) or lift the vehicle to access the fuel tank.
2. Connect the fuel pressure gauge to the fuel rail and turn the ignition on without starting the engine.
3. Verify the fuel pressure; it should be within the manufacturer’s specifications (typically 40-50 psi).
4. If pressure is low, replace the fuel pump and filter. Follow the manufacturer's manual for specific procedures.

3. Inspect Ignition System

Replace Spark Plugs:
1. Remove the engine cover (if necessary) to access the spark plugs.
2. Use a socket set to remove the old spark plugs.
3. Check the gap on new spark plugs before installation; adjust if necessary.
4. Install new spark plugs, tightening them to the manufacturer’s specified torque.
Check Ignition Coils:
1. Disconnect the electrical connectors from the ignition coils.
2. Remove the coils for inspection; check for cracks or carbon tracking.
3. Replace any damaged ignition coils with new ones.

4. Inspect Air Intake and MAF Sensor

Clean or Replace MAF Sensor:
1. Disconnect the MAF sensor wiring harness.
2. Remove the MAF sensor from the air intake.
3. Clean the sensor using MAF cleaner; do not touch the sensing element.
4. Reinstall the MAF sensor and reconnect the wiring harness.

5. Final Steps

Reconnect the negative battery terminal.
Start the engine and allow it to idle for a few minutes.
Perform a test drive to ensure the stalling issue has been resolved.
