Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, vacuum gauge, and cleaning supplies.
Safety Warnings: Disconnect the battery before working on electrical systems. Ensure the engine is cool before inspecting components.

2. Addressing Engine Mounts

Inspect Engine Mounts:
- Visually check the engine mounts for cracks, separation, or deterioration.
- Use a pry bar to check for excessive movement in the mounts.
Replace Damaged Mounts:
- Raise the vehicle securely using jack stands.
- Support the engine with a jack and a wooden block to avoid damage.
- Remove the bolts securing the damaged engine mount to the engine and chassis.
- Install the new mount and torque to manufacturer specifications (usually around 50-70 ft-lbs).

3. Cleaning Throttle Body

Remove Air Intake Duct:
- Loosen the clamps and detach the air intake duct from the throttle body.
Clean Throttle Body:
- Use throttle body cleaner spray and a clean rag to remove carbon deposits.
- Open the throttle plate manually to clean inside edges.
- Reattach the air intake duct securely.

4. Inspect and Replace Spark Plugs

Remove Spark Plugs:
- Disconnect the ignition coil connectors.
- Remove the ignition coil bolts and pull out the coils.
- Use a spark plug socket to remove the spark plugs.
Install New Spark Plugs:
- Check the gap of the new spark plugs (typically 0.043 inches for the RAV4).
- Install the new spark plugs with a torque of around 13 ft-lbs.
- Reinstall ignition coils and reconnect the connectors.
