Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Address Engine Codes

Use the OBD-II scanner to read and document error codes.
Clear the codes and perform a test drive to see if they return.

3. Inspect and Replace Spark Plugs and Ignition Coils

Remove the engine cover (if applicable) using a socket set.
Disconnect the ignition coils and remove them.
Remove the spark plugs using a spark plug socket.
Inspect spark plugs for signs of wear or fouling; replace if necessary.
Install new spark plugs and ignition coils, ensuring proper torque specifications (typically 15-20 ft-lbs for spark plugs).

4. Fuel System Inspection

Locate the fuel filter and inspect for clogs; replace if necessary.
Test the fuel pump using a fuel pressure gauge to ensure proper pressure is being delivered to the engine.
Replace the fuel pump if pressure is below manufacturer's specifications.

5. Check Engine Mounts

Visually inspect engine mounts for visible cracks or wear.
Use a jack to support the engine slightly and remove the bolts securing the mounts.
Replace damaged mounts with new ones, ensuring proper torque specifications are followed.

6. Reconnect Battery and Final Checks

Reconnect the battery terminals.
Perform a final visual inspection of all components.
Start the engine and check for normal operation.
