Problem Statement

The Alfa Romeo Giulia 952 (2016-Present) is experiencing stalling issues, which can be indicative of various underlying problems affecting engine performance and fuel delivery.

Solution

Symptoms

Engine stalls unexpectedly during idle or while driving
Rough idle when the engine is running
Check engine light illuminated on the dashboard
Difficulty starting the engine after stalling
Loss of power during acceleration
Increased engine vibrations

Diagnostic Steps

Scan for error codes using an OBD-II scanner to identify potential faults.
Inspect the fuel system, including checking fuel pressure and fuel filter condition.
Examine the ignition system components, such as spark plugs and ignition coils.
Check the air intake system for blockages or leaks, particularly in the air filter and intake hoses.
Inspect the throttle body for cleanliness and proper operation.
Assess the condition of the battery and alternator to ensure proper voltage supply.

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative terminal of the battery to prevent electrical shock.

2. Fuel System Inspection

Sub-steps:
1. Locate the fuel pressure test port on the fuel rail.
2. Connect a fuel pressure gauge to the test port.
3. Turn the ignition to the "ON" position without starting the engine to check fuel pressure; it should be within the manufacturer's specifications (typically around 58-65 psi).
4. If pressure is low, inspect the fuel pump fuse and relay, and replace if necessary.
5. Replace the fuel filter if it appears clogged or has not been changed per maintenance schedule.

3. Ignition System Check

Sub-steps:
1. Remove the engine cover if applicable to access spark plugs.
2. Inspect and replace spark plugs if they are worn or fouled (gap should be as per specifications).
3. Test ignition coils using a multimeter for resistance; replace any faulty coils.
4. Reinstall the engine cover securely after inspection.

4. Throttle Body Cleaning

Sub-steps:
1. Disconnect the throttle body electrical connectors.
2. Remove the throttle body from the intake manifold (usually requires a socket set).
3. Clean the throttle plate and surrounding area using throttle body cleaner and a soft brush.
4. Reinstall the throttle body ensuring all bolts are tightened to the specified torque.
5. Reconnect the electrical connectors securely.

5. Air Intake System Check

Sub-steps:
1. Inspect the air filter; replace if dirty or clogged.
2. Check all intake hoses for cracks or leaks; replace as necessary.
3. Ensure that the mass airflow sensor is clean; clean it with appropriate cleaner if dirty.
