Solution

1. Preparation

Gather tools and parts.
Disconnect the battery to ensure safety while working on the ignition system.
Tools required: OBD-II scanner, socket set, fuel pressure gauge, multimeter, torque wrench.

2. Address Ignition System

Remove spark plugs:
1. Using a socket wrench, remove the spark plug wires carefully.
2. Unscrew and remove the spark plugs with a spark plug socket.
Inspect and replace:
1. Check the condition of the spark plugs for wear or fouling.
2. Replace any faulty plugs with new ones, ensuring the gap is set to manufacturer specifications.
Inspect ignition coils:
1. Remove the ignition coils using a socket set.
2. Test each coil with a multimeter for proper resistance.
3. Replace any defective ignition coils.

3. Fuel System Inspection

Check fuel pressure:
1. Attach the fuel pressure gauge to the fuel rail.
2. Turn the ignition to the "ON" position without starting the engine to check pressure readings.
3. Compare the readings with manufacturer specifications.
Replace fuel filter:
1. If the pressure is low, consider replacing the fuel filter as part of routine maintenance.

4. Inspect Engine Mounts

Check engine mounts:
1. Visually inspect the engine mounts for cracks or separations.
2. Using a pry bar, check for excessive movement in the mounts.
Replace if necessary:
1. Unbolt the faulty engine mounts using a socket set.
2. Install new mounts and torque to the specified values.
