Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Engine Mounts

Tools Required: Socket set, torque wrench, pry bar
Remove the bolts securing the engine mount to the engine and the subframe using a socket set.
Use a pry bar to gently lift the engine and remove the old engine mount.
Install the new engine mount by aligning it properly and tightening bolts to the manufacturer's torque specifications.
Reconnect the negative battery terminal once done.

3. Check and Replace Spark Plugs (if needed)

Tools Required: Socket set, spark plug socket, torque wrench
Remove the engine cover if applicable.
Disconnect the ignition coils from the spark plugs.
Using a spark plug socket, remove the spark plugs and inspect them for wear or damage.
Replace with new spark plugs, ensuring they are gapped correctly to specification.
Reinstall ignition coils and engine cover.

4. Clean or Replace Fuel Injectors (if needed)

Tools Required: Fuel injector cleaner, fuel pressure gauge
If fuel injectors are suspected to be clogged, use a fuel injector cleaning solution as per the product instructions.
Alternatively, remove and replace fuel injectors if cleaning is not effective, ensuring all connections are secure.
