Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Replace Spark Plugs

Remove the engine cover (if applicable) using a socket set.
Disconnect the ignition coils by unclipping the connectors.
Remove the ignition coils using the socket set.
Remove the old spark plugs using a spark plug socket.
Install new spark plugs to the manufacturer's recommended torque specification (typically 13-15 ft-lbs).
Reinstall the ignition coils and connect the electrical connectors.
Reinstall the engine cover.

3. Check and Replace Fuel Filter (if applicable)

Locate the fuel filter in the fuel line.
Relieve fuel pressure by removing the fuel pump relay and starting the engine until it stalls.
Disconnect the fuel lines from the filter using a fuel line disconnect tool.
Replace the old filter with a new one, ensuring proper orientation.
Reconnect the fuel lines securely and reinstall the fuel pump relay.

4. Inspect and Clean 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.
Reinstall the air intake duct securely.

5. Check Transmission Fluid

Locate the transmission dipstick and remove it.
Check the fluid level and condition; it should be bright red and not have a burnt smell.
If the fluid is low, add the manufacturer-recommended transmission fluid until it reaches the proper level.
