Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Engine Mounts

Sub-steps:
- Remove any covers or components obstructing access to the engine mounts.
- Use a jack to support the engine slightly while replacing mounts.
- Remove the fasteners securing the engine mounts to the engine and chassis.
- Replace damaged or worn mounts with new OEM parts.
- Torque new mounts to manufacturer specifications (refer to service manual for exact values).

3. Replace Spark Plugs

Sub-steps:
- Remove the ignition coil or spark plug wires.
- Use a spark plug socket to remove the old spark plugs.
- Check the gap on new spark plugs and adjust if necessary.
- Install new spark plugs and torque them to the specified value.
- Reconnect ignition components.

4. Clean Fuel Injectors

Sub-steps:
- Disconnect the fuel line from the fuel rail (ensure safety precautions).
- Use a fuel injector cleaning kit to clean the injectors, following the kit's instructions.
- Reconnect the fuel line and check for leaks.

5. Check Idle Speed

Sub-steps:
- Start the engine and use a tachometer to measure the idle speed.
- If the idle speed is too high or low, adjust using the throttle body idle adjustment screw, if applicable.
- Ensure that the engine is warm during this adjustment.
