Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to ensure safety during repairs.

2. Inspect Engine Mounts

Use a socket set to remove any covers obstructing access to engine mounts.
Visually inspect each engine mount for cracks, tears, or excessive wear.
If damaged, replace with OEM or high-quality aftermarket engine mounts.

3. Check and Replace Ignition Components

Remove the ignition coil using a socket set and inspect the spark plug.
Replace worn spark plugs with OEM specifications (e.g., NGK or Denso).
Reinstall the ignition coil securely, ensuring proper torque specifications (typically around 10-15 ft-lbs).

4. Inspect Fuel System

Use a fuel pressure gauge to check for proper fuel pressure at the fuel rail.
If pressure is low, inspect the fuel filter and replace if clogged.
Ensure fuel injectors are clean; consider using a fuel injector cleaner if necessary.

5. Check Vacuum Lines

Visually inspect all vacuum lines connected to the intake manifold.
Replace any cracked or loose vacuum lines to ensure proper vacuum levels.

6. Clean Air Filter and Intake System

Remove the air filter housing using a socket set.
Inspect the air filter; replace if dirty.
Clean the intake manifold and throttle body with appropriate cleaner to remove carbon deposits.
