Solution

1. Preparation

Gather all 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. Clean the Throttle Body

Remove the air intake duct connected to the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding area.
Reattach the air intake duct securely.

3. Replace the Fuel Filter

Locate the fuel filter (check the owner's manual for its location).
Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
Disconnect the fuel lines using a fuel line disconnect tool.
Replace the old fuel filter with a new one, ensuring proper orientation.
Reconnect the fuel lines and replace the fuel pump fuse.

4. Check and Replace Transmission Fluid (if necessary)

Locate the transmission fluid dipstick; remove it and check the fluid level.
If low, add the appropriate transmission fluid as specified in the owner's manual.
If the fluid is dark or burnt, consider a full transmission fluid change.

5. Inspect Engine Mounts

Visually inspect engine mounts for cracking, splitting, or excessive wear.
If any mounts are damaged, replace them with OEM parts.
Tighten all mounting bolts to the manufacturer’s torque specifications.
