Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to avoid electrical shorts while working on the vehicle.

2. Fuel System Inspection

Tools Required: Fuel pressure gauge, screwdriver set.
Steps:
1. Connect the fuel pressure gauge to the fuel rail test port.
2. Turn the ignition key to the ON position (do not start) and check the fuel pressure reading.
3. If pressure is below specifications (consult manufacturer’s manual), replace the fuel pump.
4. If pressure is normal, proceed to check fuel filter and replace if clogged.

3. Ignition System Maintenance

Tools Required: Spark plug socket, torque wrench.
Steps:
1. Remove the ignition coils and inspect for cracks or damage.
2. Replace any faulty ignition coils.
3. Remove spark plugs, inspect for wear, and replace if necessary.
4. Install new spark plugs according to manufacturer torque specifications.

4. Throttle Body Cleaning

Tools Required: Throttle body cleaner, soft brush, clean rags.
Steps:
1. Remove the air intake duct from the throttle body.
2. Spray throttle body cleaner inside the throttle body and scrub with a soft brush.
3. Wipe clean with a rag to remove any carbon buildup.
4. Reattach the air intake duct securely.

5. Final Assembly and Testing

Steps:
1. Reconnect the battery.
2. Start the engine and monitor for any irregularities in idle.
3. Perform a test drive to verify that the stalling issue is resolved.
