Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Engine Mounts

Sub-steps:
- Lift the vehicle securely using jack stands.
- Visually inspect the engine mounts for cracks or separation.
- Remove any protective covers if necessary.
- If damaged, remove the bolts securing the mounts using a socket set.
- Replace with new engine mounts, ensuring proper alignment.
- Torque bolts to manufacturer specifications (typically around 50-70 ft-lbs, check specific model).

3. Replace Spark Plugs (If Necessary)

Sub-steps:
- Remove the ignition coil cover (if applicable).
- Disconnect ignition coils and remove them using a socket set.
- Remove old spark plugs using a spark plug socket and extension.
- Inspect the gap on new spark plugs and adjust to specifications (usually 0.044 inches for a Camry).
- Install new spark plugs and reconnect ignition coils.

4. Check and Clean Fuel Injectors

Sub-steps:
- Remove the fuel rail, carefully disconnecting any electrical connectors and fuel lines (use caution as fuel may spill).
- Inspect injectors for clogs; use a fuel injector cleaning kit if necessary.
- Reinstall the fuel rail and ensure all connections are secure.
