Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Inspect and Replace Engine Mounts

Visual Inspection
- Inspect the engine mounts for cracks or signs of wear.
Remove Engine Mounts
- Use a socket set to remove the bolts securing the damaged engine mounts.
- Carefully lift the engine with an engine hoist to relieve pressure on the mounts.
- Remove the old engine mounts.
Install New Engine Mounts
- Position new mounts in place and secure with bolts. Torque to manufacturer specifications (typically around 50-60 ft-lbs).
- Lower the engine back onto the mounts.

3. Clean the Throttle Body

Remove Throttle Body
- Disconnect the throttle body electrical connector.
- Remove vacuum hoses and bolts holding the throttle body in place.
Clean the Throttle Body
- Use throttle body cleaner and a soft brush to remove carbon build-up.
- Wipe clean with a lint-free cloth.
Reinstall Throttle Body
- Reattach the throttle body and reconnect all hoses and electrical connectors, ensuring a secure fit.

4. Check Power Steering Fluid

Inspect Fluid Level
- Locate the power steering reservoir and check the fluid level against the markings.
Top Off Fluid
- If low, add the manufacturer-recommended power steering fluid.
Check for Leaks
- Inspect hoses and connections for leaks and replace any damaged components.
