Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is off.
Gather tools and equipment: OBD-II scanner, socket set, torque wrench, multimeter, and vacuum gauge.

2. Engine Mount Inspection

Remove necessary covers: Use a socket set to remove any plastic engine covers that obstruct access to engine mounts.
Check mounts visually: Inspect all engine mounts for cracks, separations, or excessive wear.
Test mount integrity: With the engine running, gently apply throttle while observing engine movement. Excessive movement indicates a faulty mount.
Replace if necessary: If any mounts are damaged, use a torque wrench to install new mounts to manufacturer specifications.

3. Spark Plug Replacement

Remove spark plug wires: Carefully disconnect the spark plug wires, taking care to label them for reinstallation.
Remove spark plugs: Use a spark plug socket to remove old spark plugs from the engine.
Install new spark plugs: Gap the new spark plugs to manufacturer specifications and install them using a torque wrench.
Reconnect wires: Reattach the spark plug wires in the correct order.

4. Idle Speed Adjustment

Check throttle body: Inspect the throttle body for carbon buildup and clean if necessary using throttle body cleaner.
Adjust idle speed: If the idle speed is outside the normal range, adjust it via the throttle position sensor or idle air control valve according to service manual specifications.
