Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Check Fuel System

Sub-step 1: Remove the fuel pump relay and connect a fuel pressure gauge to the fuel rail.
Sub-step 2: Turn the ignition to the "ON" position (do not start the engine) and check the fuel pressure reading. It should be within the manufacturer's specified range.
Sub-step 3: If the pressure is low, inspect the fuel pump and fuel filter for issues. Replace if necessary.

3. Inspect Air Intake System

Sub-step 1: Remove the air filter cover and check the air filter. Replace if dirty or clogged.
Sub-step 2: Inspect intake hoses for cracks or disconnections and replace any damaged components.

4. Examine Ignition System

Sub-step 1: Remove spark plug wires and inspect the spark plugs for wear or fouling.
Sub-step 2: Replace any faulty spark plugs and ignition coils as needed.

5. Clean Throttle Body

Sub-step 1: Remove the throttle body from the intake manifold.
Sub-step 2: Use a throttle body cleaner and a soft cloth to clean the interior surfaces. Ensure the throttle plate moves freely.
Sub-step 3: Reinstall the throttle body and reconnect all hoses and electrical connectors.

6. Check for Vacuum Leaks

Sub-step 1: Use a smoke machine or carburetor cleaner to test for vacuum leaks in the intake manifold.
Sub-step 2: Repair or replace any identified leaks.
