Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the negative battery terminal for safety.

2. Inspect and Replace Engine Mounts

Access Engine Mounts
- Lift the vehicle using a jack and secure it with jack stands.
- Remove any components obstructing access to the engine mounts (e.g., splash shields).
Check Engine Mounts
- Visually inspect for cracks or excessive wear.
- Use a pry bar to test for movement; if they shift significantly, they need replacement.
Replace Engine Mounts
- Remove the bolts securing the old mounts using a socket set.
- Install new engine mounts, ensuring they are aligned properly.
- Torque bolts to manufacturer specifications (consult service manual for exact torque values).

3. Clean Throttle Body

Remove Air Intake Duct
- Loosen clamps and detach the air intake duct from the throttle body.
Clean Throttle Body
- Use throttle body cleaner and a soft brush to clean the throttle plate and bore.
- Ensure all carbon deposits are removed for smooth operation.
Reassemble
- Reattach the air intake duct and secure clamps properly.

4. Replace Spark Plugs (if necessary)

Remove Ignition Coils
- Disconnect the wiring harness from each ignition coil and remove them with a socket.
Remove Old Spark Plugs
- Use a spark plug socket to unscrew and remove old spark plugs.
Install New Spark Plugs
- Apply anti-seize lubricant to threads and install new spark plugs, ensuring correct gap.
- Reattach ignition coils and wiring harnesses.
