Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.
Raise the vehicle on jack stands if inspecting undercarriage components.

2. Inspect and Replace Engine Mounts

Tools Required: Socket set, torque wrench
Steps:
1. Visually inspect engine mounts for cracks or excessive wear.
2. If damaged, remove the bolts securing the mount to the engine and the frame.
3. Replace with new engine mounts, ensuring proper alignment.
4. Torque bolts to manufacturer specifications (typically around 40-50 ft-lbs).

3. Check and Replace Transmission Fluid

Tools Required: Transmission fluid pump, catch pan
Steps:
1. Locate the transmission fluid dipstick and check the fluid level.
2. If low, add the appropriate type of transmission fluid (typically Toyota ATF WS).
3. If fluid is dark or burnt, perform a transmission fluid change:
  - Remove the transmission pan and filter.
  - Replace the filter and clean the pan.
  - Refill with new transmission fluid, ensuring proper level.

4. Inspect and Replace Spark Plugs

Tools Required: Spark plug socket, torque wrench
Steps:
1. Remove the ignition coils or spark plug wires.
2. Unscrew the old spark plugs and inspect for wear.
3. Replace with new spark plugs, torquing to manufacturer's specifications (typically around 13-16 ft-lbs).

5. Clean Throttle Body

Tools Required: Throttle body cleaner, soft brush, rags
Steps:
1. Remove the intake duct to access the throttle body.
2. Spray throttle body cleaner onto the throttle plate and use a soft brush to clean.
3. Wipe away any residue with a clean rag and reassemble.
