Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the battery to ensure safety during work.
Make sure the vehicle is on a flat surface and secured with wheel chocks.

2. Inspect Fuel System

Sub-step 1: Check the fuel pump operation by listening for a humming sound when the ignition is turned on.
Sub-step 2: Use a fuel pressure gauge to measure fuel pressure at the rail; it should match manufacturer specifications (typically around 50-60 psi).
Sub-step 3: If pressure is low, check the fuel pump relay and wiring; replace the fuel pump if necessary.

3. Check Ignition System

Sub-step 1: Remove the spark plugs and inspect for wear or carbon buildup; replace if necessary.
Sub-step 2: Test each ignition coil with a multimeter to ensure they are within the correct resistance range (usually 0.4 to 2 ohms).
Sub-step 3: Replace any faulty ignition coils.

4. Examine Air Intake System

Sub-step 1: Remove the air filter and inspect it for dirt and debris; replace if clogged.
Sub-step 2: Check the intake manifold for cracks or loose connections.
Sub-step 3: Inspect and clean the throttle body using throttle body cleaner, ensuring the plate can open and close freely.

5. Check for Vacuum Leaks

Sub-step 1: Use a smoke machine or carburetor cleaner to find leaks in vacuum lines.
Sub-step 2: Replace any damaged hoses or gaskets found during inspection.
