Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface, and engage the parking brake.
Disconnect the battery terminal 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 areas.
Reconnect the air intake duct securely.

3. Replace the Fuel Filter

Locate the fuel filter (usually along the fuel line).
Relieve fuel system pressure by removing the fuse for the fuel pump and starting the engine until it stalls.
Disconnect the fuel lines from the filter using appropriate line wrenches.
Install the new fuel filter, ensuring correct flow direction, and reconnect the fuel lines.

4. Replace Spark Plugs and Ignition Coils

Remove the ignition coil cover if applicable.
Disconnect the electrical connectors from the ignition coils.
Remove the bolts securing the coils and lift them out.
Replace spark plugs using a spark plug socket, following the manufacturer’s torque specifications (usually 13-20 lb-ft).
Reinstall the ignition coils and reconnect their electrical connectors.

5. Check Transmission Fluid

With the vehicle running, check the transmission fluid level using the dipstick.
If low, add the correct type of transmission fluid as specified in the owner’s manual.
Inspect the fluid condition; if dark or burnt, consider a transmission flush.
