Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Allow the engine to cool if it has been running.

2. Address Faulty Components

A. Spark Plugs and Ignition Coils

Remove Engine Cover (if applicable)
- Use a socket set to remove bolts securing the cover.
Unplug Ignition Coils
- Carefully disconnect the electrical connectors from each ignition coil.
Remove Ignition Coils
- Unscrew the bolts holding the coils in place and lift them out.
Replace Spark Plugs
- Use a spark plug socket to remove old spark plugs and install new ones, tightening to the manufacturer’s torque specifications (generally around 13 ft-lbs).

B. Inspect Fuel Injectors

Access Fuel Rail
- Remove any components obstructing access to the fuel rail (e.g., intake manifold).
Test Injectors
- Use a multimeter to check resistance across the injectors. Replace any that are out of specification.
Clean or Replace Injectors
- If needed, use a fuel injector cleaning kit or replace with new injectors.

3. Inspect Engine Mounts

Visual Inspection
- Check for cracks or excessive wear on engine mounts.
Replace Damaged Mounts
- Use a socket set to remove and replace any damaged mounts, tightening to specified torque values.
