Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery cable to prevent any electrical shorts.
Allow the engine to cool completely before proceeding.

2. Inspect and Replace Engine Mounts

Sub-step 1: Locate the engine mounts (typically at the front, rear, and sides of the engine).
Sub-step 2: Using a socket set, remove the bolts securing the affected engine mounts.
Sub-step 3: Lift the engine slightly using a jack and a block of wood to relieve pressure on the mounts.
Sub-step 4: Remove the old engine mounts and replace them with new mounts, ensuring they are oriented correctly.
Sub-step 5: Torque the mounting bolts to the manufacturer's specifications (refer to repair manual for exact torque values).

3. Check and Adjust Idle Speed

Sub-step 1: Reconnect the negative battery cable and start the engine.
Sub-step 2: Allow the engine to reach normal operating temperature.
Sub-step 3: Use a tachometer to check the idle speed; adjust if necessary by following the vehicle’s idle adjustment procedure.

4. Clean Fuel Injectors (if necessary)

Sub-step 1: Remove the fuel rail to access the fuel injectors.
Sub-step 2: Use a fuel injector cleaner or ultrasonic cleaner to clean the injectors.
Sub-step 3: Reinstall the fuel rail and reconnect all hoses and electrical connectors.
