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. Addressing Engine Performance

Replace Spark Plugs:
- Remove the ignition coils by unbolting and gently pulling them out.
- Use a spark plug socket to remove old spark plugs.
- Install new spark plugs, ensuring they are gapped correctly according to the manufacturer specifications (typically around 0.044 inches).
- Reinstall ignition coils and secure them properly.
Replace Air Filter:
- Open the air intake box by removing screws or clips.
- Lift out the old air filter and clean the box interior.
- Install the new air filter and reassemble the intake box.

3. Transmission Fluid Check and Replacement

Check and Replace Transmission Fluid:
- Locate the transmission dipstick and check fluid level; add fluid if low.
- If the fluid appears dark or burnt, drain the transmission fluid using a pan and replace it with the manufacturer's recommended type (usually Honda CVT Fluid).
- Refill the transmission through the dipstick tube and check the level again, ensuring it is within the acceptable range.

4. Inspect and Replace Motor Mounts (if necessary)

Inspect Motor Mounts:
- Visually check motor mounts for cracks or excessive wear.
- If damaged, support the engine with a jack and remove the bolts securing the motor mount.
- Replace with new motor mounts and torque bolts to manufacturer specifications.
