Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to ensure safety during inspection.

2. Inspect Engine Mounts

Remove the engine cover (if applicable) to access engine mounts.
Visually inspect each engine mount for cracks, separation, or excessive wear.
Use a pry bar to check for excessive movement in mounts.
Replace any damaged mounts using a socket set to remove the mounting bolts.

3. Check Spark Plugs and Ignition Coils

Remove the ignition coil cover to access the spark plugs.
Use a spark plug socket to remove and inspect each spark plug for wear or carbon buildup.
Replace any faulty spark plugs with the manufacturer-recommended type and torque to specification.
Inspect the ignition coils for damage and replace if necessary.

4. Inspect Vacuum Lines

Follow the vacuum lines from the intake manifold and inspect for cracks or disconnections.
Replace any damaged vacuum hoses with high-quality replacements.

5. Fuel System Inspection

Connect a fuel pressure gauge to the fuel rail.
Turn on the ignition (do not start the engine) and check for proper fuel pressure.
Replace the fuel filter if pressure is below specifications or if it appears clogged.
