Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and set the parking brake.
Disconnect the battery before performing any electrical work.

2. Address Ignition System Issues

Sub-step 1: Remove engine cover (if applicable) using a socket set.
Sub-step 2: Inspect and replace spark plugs if worn or damaged. Use the manufacturer-recommended spark plugs and torque them to specifications (typically around 22 Nm).
Sub-step 3: Check ignition coils for faults; replace any faulty coils.

3. Repair Fuel System

Sub-step 1: Inspect the fuel filter for clogs; replace it if necessary.
Sub-step 2: Test fuel pump operation with a fuel pressure gauge; replace if pressure is below specifications.
Sub-step 3: Clean fuel injectors with a professional cleaning kit if carbon buildup is suspected.

4. Check for Vacuum Leaks

Sub-step 1: Visually inspect all vacuum hoses for cracks or disconnections.
Sub-step 2: Use a smoke machine or propane to detect vacuum leaks; repair or replace damaged hoses as needed.

5. Reassemble and Reset

Sub-step 1: Reinstall any components removed during inspection and repair.
Sub-step 2: Reconnect the battery and clear codes using the OBD-II scanner.
Sub-step 3: Start the engine and monitor for any issues.
