Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Ensure the workspace is clean and well-ventilated.

2. Inspect Fuel System

Fuel Pump
- Sub-step 1: Locate the fuel pump; it is usually within the fuel tank.
- Sub-step 2: Connect a fuel pressure gauge to the fuel rail.
- Sub-step 3: Turn the ignition to the "ON" position without starting the engine and check pressure readings. It should be within 43-50 psi.
- Sub-step 4: If pressure is low, replace the fuel pump.
Fuel Filter
- Sub-step 1: Locate the fuel filter along the fuel line.
- Sub-step 2: Disconnect the fuel lines (caution: fuel may spill).
- Sub-step 3: Replace the fuel filter with a new one, ensuring proper orientation.

3. Inspect Ignition System

Spark Plugs
- Sub-step 1: Remove the ignition coils by unscrewing the retaining bolts.
- Sub-step 2: Extract the spark plugs using a spark plug socket.
- Sub-step 3: Inspect spark plugs for wear, carbon buildup, or damage; replace if necessary.
Ignition Coils
- Sub-step 1: Visually inspect ignition coils for cracks or corrosion.
- Sub-step 2: Test each coil with a multimeter for proper resistance.
- Sub-step 3: Replace any faulty ignition coils.

4. Clean Throttle Body

Throttle Body
- Sub-step 1: Remove the air intake duct to access the throttle body.
- Sub-step 2: Use throttle body cleaner and a soft cloth to clean the inside of the throttle body.
- Sub-step 3: Reattach the air intake duct securely.

5. Reassemble and Test

Sub-step 1: Reconnect the negative battery terminal.
Sub-step 2: Start the engine and let it idle to check for smooth operation.
Sub-step 3: Test drive the vehicle to ensure no stalling occurs.
