Solution

1. Preparation

Gather tools: OBD-II scanner, fuel pressure gauge, socket set, multimeter, torque wrench.
Disconnect the battery to ensure safety when working on electrical components.

2. Clean or Replace Throttle Body

Remove the air intake duct connected to the throttle body using a socket set.
Disconnect the throttle position sensor and any electrical connectors.
Use throttle body cleaner and a soft cloth to clean the throttle plate and housing. Avoid using abrasive materials.
Reinstall the throttle body and reconnect the electrical connectors.
Reattach the air intake duct and ensure all clamps are secure.

3. Check and Replace Fuel Filter

Locate the fuel filter; refer to the vehicle’s service manual for specific location.
Relieve fuel system pressure by removing the fuel pump relay and running the engine until it stalls.
Disconnect the fuel lines from the filter using a line wrench.
Remove the old fuel filter and install a new one, ensuring the flow direction is correct.
Reconnect the fuel lines and reinstall the fuel pump relay.
Turn the ignition to the "ON" position (without starting) to prime the fuel system.

4. Inspect and Replace Spark Plugs/Ignition Coils

Remove the engine cover if applicable.
Disconnect the ignition coil connectors and remove the bolts securing the coils.
Pull out the ignition coils and inspect for cracks or damage; replace if necessary.
Use a spark plug socket to remove the spark plugs; check for wear or carbon buildup and replace as needed.
Install new spark plugs and torque to manufacturer specifications.
Reinstall ignition coils and connectors.

5. Transmission Fluid Inspection/Change

Check the transmission fluid level with the dipstick; add fluid if low.
If the fluid is dark or smells burnt, consider changing the fluid and filter.
To change, remove the transmission pan and drain the old fluid.
Replace the filter and reinstall the pan, torquing bolts to manufacturer specifications.
Refill with the recommended transmission fluid type.
