Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery cable to ensure safety.
Allow the engine to cool before starting work.

2. Replace Spark Plugs

Remove the engine cover (if applicable).
Use a socket wrench to remove the spark plug wires or ignition coil.
Use a spark plug socket to remove old spark plugs.
Inspect and clean the spark plug holes.
Install new spark plugs, tightening to the manufacturer's specified torque (typically 13-15 lb-ft).
Reconnect ignition coils or spark plug wires.

3. Inspect and Replace Engine Mounts

Locate the engine mounts (typically near the front and rear of the engine).
Use a socket set to remove the bolts securing the engine mounts.
Lift the engine slightly using a jack (with a block of wood to protect the oil pan).
Remove the old engine mounts and replace with new ones.
Torque the bolts to the manufacturer's specifications.

4. Check and Clean Fuel Injectors

Remove the fuel injector connectors carefully.
Use a fuel injector cleaning kit or remove injectors for ultrasonic cleaning.
Reinstall cleaned or new fuel injectors, ensuring proper alignment.
Reconnect the fuel injector connectors.

5. Inspect and Repair Air Intake

Check the air filter and replace if dirty.
Inspect the intake hose for cracks or loose connections.
Tighten any loose clamps and replace damaged hoses.
