Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, fuel pressure gauge, vacuum gauge.
Instructions:
- Ensure the vehicle is parked on a level surface and the engine is cool before beginning work.
- Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Engine Mounts

Instructions:
- Lift the vehicle safely using jack stands.
- Locate the engine mounts; they are typically found at the front, rear, and sides of the engine.
- Use a socket set to remove the bolts securing the mounts to the engine and frame.
- Inspect the mounts for cracks or fluid leaks. If damaged, replace with OEM parts.
- Position the new mounts in place and torque the bolts to the manufacturer’s specifications (typically around 25-30 ft-lbs).

3. Check and Replace Ignition Components

Instructions:
- Remove the engine cover if applicable.
- Disconnect the ignition coils from the spark plugs.
- Use a multimeter to test each ignition coil for resistance; replace any that are out of spec.
- Remove old spark plugs and check for wear. Replace them with the correct OEM spark plugs, torqued to the specified value (usually 15-20 ft-lbs).
- Reconnect ignition coils.

4. Inspect Fuel Delivery System

Instructions:
- Locate the fuel rail and connect a fuel pressure gauge.
- Start the engine and check the fuel pressure; it should be within the manufacturer’s specification (typically around 50-60 PSI).
- If pressure is low, inspect the fuel filter and pump for blockages or failure; replace as necessary.

5. Check for Vacuum Leaks

Instructions:
- With the engine running, use a vacuum gauge to check for proper readings.
- Inspect all vacuum hoses and connections, replacing any that are cracked or loose.
