Solution

1. Preparation

• Gather tools and parts required for the repair.
• Disconnect the battery to prevent electrical shorts.
• Allow engine to cool before starting any work.

2. Inspect and Replace Engine Mounts

• Step 1: Raise the vehicle using a jack and secure it with jack stands.
• Step 2: Locate the engine mounts; typically found at the front and rear of the engine.
• Step 3: Using a socket set, remove the bolts securing the engine mounts.
• Step 4: Remove the old engine mounts from their positions.
• Step 5: Install the new engine mounts in the reverse order, ensuring they are torqued to manufacturer specifications (usually around 40-50 Nm).
• Tools Required: Socket set, torque wrench, jack stands.

3. Replace Spark Plugs and Ignition Coils (if faulty)

• Step 1: Remove the engine cover if applicable.
• Step 2: Disconnect the wiring harness from the ignition coils.
• Step 3: Remove the ignition coils using a socket set.
• Step 4: Replace the spark plugs using a spark plug socket, ensuring they are gapped correctly (typically 0.6-0.7 mm).
• Step 5: Reassemble the ignition coils and wiring harness.
• Tools Required: Spark plug socket, socket set, gap tool.

4. Check Fuel System (if necessary)

• Step 1: Connect a fuel pressure gauge to the fuel rail.
• Step 2: Turn the ignition on (do not start the engine) to check the fuel pressure reading; it should match manufacturer specifications (usually around 3-5 bar).
• Step 3: If fuel pressure is low, inspect the fuel pump and filter for issues and replace if necessary.
• Tools Required: Fuel pressure gauge.
