Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is parked on a level surface.
Disconnect the battery to avoid any electrical shorts during inspection.
Tools Required: OBD-II scanner, socket set, torque wrench, vacuum gauge, fuel pressure gauge.

2. Inspect Engine Mounts

Sub-steps:
1. Visually inspect the engine mounts for cracks, excessive wear, or separation.
2. Use a pry bar to gently check for movement in the mounts; they should be firm and stable.
3. If damaged, proceed to replace the engine mounts.
Parts Required: Replacement engine mounts (if necessary).

3. Check for Vacuum Leaks

Sub-steps:
1. Start the engine and let it idle.
2. Use a vacuum gauge or spray soapy water around the intake manifold and vacuum hoses.
3. Look for fluctuating readings on the gauge or bubbles indicating leaks.
Parts Required: Vacuum hoses (if leaks are found).

4. Inspect Spark Plugs and Ignition System

Sub-steps:
1. Remove spark plugs using a socket set and inspect for wear, carbon buildup, or damage.
2. Check ignition coils for proper function and replace any faulty components.
3. Reinstall spark plugs with specified torque (usually around 13-15 lb-ft).
Parts Required: New spark plugs and ignition coils (if needed).

5. Test Fuel System Pressure

Sub-steps:
1. Connect a fuel pressure gauge to the fuel rail.
2. Turn the ignition to the "ON" position (without starting) to check pressure.
3. Compare readings to manufacturer specifications and address any discrepancies.
Parts Required: Fuel pressure regulator (if pressure is low).

6. Clean Throttle Body

Sub-steps:
1. Remove the intake duct to access the throttle body.
2. Use throttle body cleaner to remove carbon buildup from the throttle plate and body.
3. Reassemble the intake system and reconnect the battery.
Parts Required: Throttle body cleaner.
