Solution

1. Preparation

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

2. Inspect and Replace Engine Mounts

Tools Required: Socket set, torque wrench, pry bar
Sub-steps:
1. Lift the vehicle with a jack and secure it with jack stands.
2. Locate the engine mounts (typically near the front and rear of the engine).
3. Visually inspect the mounts for cracks, tears, or separation.
4. If damaged, unbolt the engine mount using the socket set.
5. Replace with new engine mounts and torque bolts to manufacturer's specifications (usually around 40-50 ft-lbs).

3. Check and Replace Spark Plugs

Tools Required: Spark plug socket, torque wrench, gap gauge
Sub-steps:
1. Remove the engine cover if applicable to access the spark plugs.
2. Disconnect the ignition coil connectors.
3. Remove the ignition coils and set them aside.
4. Unscrew old spark plugs using the spark plug socket.
5. Check the gap on new spark plugs using a gap gauge and adjust as necessary.
6. Install new spark plugs and torque them to manufacturer specifications (typically 13-16 ft-lbs).

4. Inspect Fuel Injectors

Tools Required: Fuel pressure gauge, injector cleaner (if necessary)
Sub-steps:
1. Connect a fuel pressure gauge to the fuel rail to check for proper fuel pressure according to specifications.
2. If pressure is low, consider cleaning or replacing fuel injectors.
3. Use an injector cleaner or replace faulty injectors as needed, ensuring proper installation.
