Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Inspect and Clean Throttle Body

Tools Required: Throttle body cleaner, soft brush, microfiber cloth.
Remove the air intake duct connected to the throttle body.
Spray throttle body cleaner into the throttle body while opening the throttle plate manually.
Use a soft brush to gently scrub any carbon buildup, then wipe clean with a microfiber cloth.
Reattach the air intake duct and ensure all clamps are secure.

3. Check Fuel System

Tools Required: Fuel pressure gauge.
Disconnect the fuel pump relay to prevent the pump from operating.
Connect a fuel pressure gauge to the fuel rail test port.
Turn the ignition to the "ON" position (do not start) to check fuel pressure; it should be within the manufacturer's specified range.
If pressure is low, inspect and replace the fuel pump if necessary.

4. Inspect Ignition Components

Tools Required: Socket set, torque wrench.
Remove the ignition coil cover.
Unplug and remove each ignition coil and inspect for cracks or damage.
Replace any faulty ignition coils and ensure they are torqued to the manufacturer's specifications.
Check spark plugs for wear and replace if necessary.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the engine and allow it to idle. Monitor for any irregularities.
Test drive the vehicle to check if stalling persists.
