Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the negative battery terminal to ensure safety during repairs.

2. Inspect Engine Mounts

Sub-steps:
1. Visually inspect each engine mount for cracks or separation.
2. Use a jack to lift the engine slightly to relieve tension on the mounts.
3. Replace any damaged engine mounts with OEM parts.
Tools Required: Socket set, jack, jack stands

3. Replace Spark Plugs and Coils

Sub-steps:
1. Remove the engine cover if necessary to access the spark plugs.
2. Disconnect the ignition coil connectors and remove the coils.
3. Remove the old spark plugs using a spark plug socket.
4. Install new spark plugs and ensure they are torqued to manufacturer specifications (typically 13-16 lb-ft).
5. Reinstall the ignition coils and reconnect the connectors.
Tools Required: Torque wrench, spark plug socket, ratchet

4. Clean Fuel Injectors

Sub-steps:
1. Remove the fuel rail to access the injectors.
2. Use a fuel injector cleaning kit to clean each injector according to the manufacturer’s instructions.
3. Reassemble the fuel rail and ensure all connections are secure.
Tools Required: Fuel injector cleaning kit, socket set
