Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Address the Check Engine Light

Sub-step 1: Use the OBD-II scanner to retrieve error codes.
Sub-step 2: Document all codes and research potential causes based on the codes.
Sub-step 3: Clear the codes and see if they reappear after a test drive.

3. Inspect and Replace Spark Plugs and Ignition Coils

Sub-step 1: Remove the engine cover (if applicable) using a socket set.
Sub-step 2: Disconnect the ignition coil harness, remove bolts securing the coils, and take out the coils.
Sub-step 3: Remove the spark plugs using a spark plug socket; inspect for wear and replace if necessary.
Sub-step 4: Install new spark plugs and ignition coils in reverse order, ensuring to torque plugs to manufacturer's specifications (typically 13-15 lb-ft).

4. Check Fuel Delivery System

Sub-step 1: Inspect the fuel pump operation using a fuel pressure gauge.
Sub-step 2: If pressure is low, consider replacing the fuel pump.
Sub-step 3: Inspect fuel injectors for clogs; clean or replace as needed.

5. Inspect Engine Mounts

Sub-step 1: Visually inspect engine mounts for cracks or separation.
Sub-step 2: Replace any damaged engine mounts, ensuring to torque bolts to proper specifications.

6. Vacuum and Air Intake System Inspection

Sub-step 1: Check all vacuum hoses for cracks or disconnections; replace any faulty hoses.
Sub-step 2: Remove the air filter and inspect for dirt or blockages; replace if necessary.
