Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the old air filter and visually inspect it for dirt or damage.
Install a new air filter that meets OEM specifications.
Reassemble the air filter housing cover.

3. Clean Throttle Body

Remove the throttle body by disconnecting the electrical connectors and the intake duct.
Use throttle body cleaner and a soft cloth to clean the interior surfaces.
Reinstall the throttle body and reconnect all connectors and ducts.

4. Inspect and Replace Spark Plugs

Remove the ignition coil cover using a socket set.
Disconnect the ignition coils and remove them.
Unscrew the old spark plugs using a spark plug socket.
Install new spark plugs with the correct gap settings and torque to manufacturer specifications.
Reinstall ignition coils and the cover.

5. Check Fuel Pressure

Connect a fuel pressure gauge to the fuel rail.
Turn the ignition to the "ON" position (do not start the engine) and check pressure readings.
If pressure is low, consider replacing the fuel pump or fuel filter depending on the results.

6. Inspect Transmission Fluid

Check the transmission fluid level with the dipstick while the engine is running.
If low, add the appropriate type of automatic transmission fluid (ATF) to the specified level.
If fluid appears burnt or dirty, consider a transmission fluid change.
