Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, compression tester, vacuum gauge.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Replace Worn Engine Mounts

Sub-steps:
1. Lift and secure the vehicle using jack stands.
2. Remove the nuts/bolts securing the engine mount to the engine block using a socket set.
3. Support the engine with an engine hoist or jack if necessary to relieve pressure on the mounts.
4. Remove the old engine mount and install the new mount, ensuring proper alignment.
5. Torque the bolts to the manufacturer’s specifications (typically found in the service manual).

3. Address Vacuum Leaks

Sub-steps:
1. Use a vacuum gauge to check the intake manifold vacuum.
2. If low vacuum is detected, inspect hoses and connections for cracks or disconnections.
3. Replace any damaged vacuum hoses and ensure all connections are secure.

4. Replace Spark Plugs

Sub-steps:
1. Remove the ignition coil or cover to access the spark plugs.
2. Use a socket to remove old spark plugs and inspect them for wear.
3. Install new spark plugs, ensuring the correct gap is set (refer to service manual for specifications).
4. Reattach the ignition coil or cover after securing the new plugs.

5. Clean Fuel Injectors

Sub-steps:
1. Disconnect the fuel lines from the fuel injectors using appropriate tools.
2. Use a fuel injector cleaning kit or have them professionally cleaned.
3. Reinstall the cleaned injectors and reconnect fuel lines, ensuring no leaks.
