Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent any electrical issues during the repair.

2. Inspect Engine Mounts

Tools Required: Socket set, torque wrench
Remove the bolts securing the engine mounts using the socket set.
Inspect the mounts for cracks, tears, or excessive wear. If damaged, replace with new mounts.
Torque the new engine mounts to specifications as per the service manual.

3. Check for Vacuum Leaks

Tools Required: Smoke machine or carburetor cleaner
Connect the smoke machine to the intake system to check for leaks. Alternatively, spray carburetor cleaner around the vacuum hoses while the engine is running and observe for changes in idle.
If a leak is identified, replace the faulty hose or seal.

4. Clean Fuel Injectors

Tools Required: Fuel injector cleaning kit or professional cleaning service
Remove the fuel injectors from the engine, following the manufacturer's guidelines.
Use the cleaning kit to flush the fuel injectors or take them to a professional for ultrasonic cleaning.
Reinstall the injectors and ensure all connections are secure.

5. Replace Spark Plugs and Ignition Coils

Tools Required: Socket set, torque wrench
Remove the spark plug wires or ignition coil connectors.
Unscrew the spark plugs using the socket set and inspect for wear. If they appear worn or fouled, replace them with OEM specifications.
If ignition coils are faulty, replace them at this time.
Reinstall all components and torque to specifications.
