Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, fuel pressure gauge, inspection mirror.
Disconnect the battery negative terminal to ensure safety while working on the vehicle.
Allow the engine to cool before proceeding.

2. Inspect and Replace Spark Plugs

Remove the engine cover (if applicable) using a socket set.
Disconnect the ignition coils and remove them from the spark plugs.
Use a socket wrench to remove the old spark plugs.
Inspect the spark plugs for wear and gap; replace with OEM specifications if necessary (typically NGK or Denso plugs).
Torque the new spark plugs to manufacturer specifications (usually around 13 lb-ft).
Reinstall the ignition coils and engine cover.

3. Check and Replace Engine Mounts (if damaged)

Inspect engine mounts visually and check for cracks or excessive wear.
If damaged, support the engine with a jack and remove the bolts securing the engine mount to the engine and chassis.
Replace with OEM engine mounts, ensuring proper alignment.
Torque the mount bolts to manufacturer specifications.

4. Clean or Replace Air Filter

Locate the air intake box and open it.
Remove the air filter and inspect for dirt and debris.
Clean if reusable, or replace with a new air filter as necessary.
Reassemble the air intake box securely.

5. Inspect Fuel Injectors

Connect a fuel pressure gauge to the fuel rail.
Start the engine and monitor fuel pressure; it should be within manufacturer specifications (typically around 30-50 psi).
If pressure is low, inspect for clogged fuel injectors and clean or replace as needed.
