Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, vacuum gauge.
Disconnect the negative battery cable and allow the engine to cool before starting repairs.

2. Inspect and Replace Engine Mounts

Lift the Vehicle: Use a jack to lift the front of the vehicle and secure it with jack stands.
Locate Engine Mounts: Identify the engine mounts, typically found on either side of the engine and under the front.
Remove Mount Bolts: Using a socket set, remove the bolts securing the engine mounts to the engine and chassis.
Inspect Mounts: Check for cracks, tears, or excessive wear in the rubber of the mounts.
Replace Mounts: If damaged, install new engine mounts by reversing the removal steps. Ensure bolts are torqued to manufacturer specifications.

3. Check and Replace Spark Plugs

Remove Ignition Coils: Unscrew and detach ignition coils from the spark plugs using a socket.
Extract Spark Plugs: Use a spark plug socket to remove the old spark plugs from the engine.
Inspect Spark Plugs: Check for wear, fouling, or improper gap; replace if necessary.
Install New Spark Plugs: Install new spark plugs with the proper torque specifications.
Reattach Ignition Coils: Secure ignition coils back into place.

4. Inspect Fuel Injectors

Access Fuel Injectors: Remove any necessary engine covers to access the fuel rail and injectors.
Check Injector Operation: Using a multimeter, test the resistance of each fuel injector.
Clean or Replace Injectors: If injectors are clogged, clean them using an injector cleaner or replace them if faulty.
