Solution

1. Preparation

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

2. Inspect Engine Mounts

Sub-steps:
- Visually inspect engine mounts for cracks or separation.
- Use a pry bar to check for excessive play in the mounts.
- If damaged, remove the old mount by unbolting it from the engine and chassis.
- Install the new engine mount, torque bolts to manufacturer specifications (typically around 40-50 ft-lbs).

3. Check and Replace Spark Plugs

Sub-steps:
- Remove spark plug wires and use a spark plug socket to unscrew the plugs.
- Inspect the old spark plugs for wear, carbon buildup, or damage.
- Gap new spark plugs according to specifications (usually around 0.043 inches for Camry).
- Install new spark plugs, tightening to a torque of 13-16 ft-lbs.

4. Clean Throttle Body

Sub-steps:
- Remove the air intake duct to access the throttle body.
- Spray throttle body cleaner onto a clean cloth and wipe the inside of the throttle body to remove carbon buildup.
- Reattach the air intake duct and ensure all clamps are secure.

5. Test and Replace Ignition Coils (if necessary)

Sub-steps:
- Disconnect the electrical connector from the ignition coil.
- Remove the coil from the engine using a socket.
- Test the coil using a multimeter; replace if out of specification.
- Install new ignition coils and reconnect the electrical connectors.
