Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and set the parking brake.
Disconnect the battery to prevent electrical shorts.

2. Replace Spark Plugs

Remove the ignition coil covers using a socket set.
Disconnect the electrical connectors from the ignition coils.
Remove the ignition coils and inspect them for wear.
Unscrew the old spark plugs using a spark plug socket and replace with new ones.
Reinstall the ignition coils and reconnect electrical connectors.

3. Fuel System Inspection

Locate the fuel rail and connect the fuel pressure gauge.
Turn the ignition to the "on" position without starting the engine and read the pressure.
If pressure is below specifications, replace the fuel pump.
Clean the fuel injectors using a fuel injector cleaner or replace them if necessary.

4. Clean the Throttle Body

Remove the throttle body from the intake manifold.
Use throttle body cleaner and a soft cloth to clean the inside of the throttle body.
Reinstall the throttle body with new gaskets to prevent air leaks.

5. Transmission Fluid Change (if necessary)

Drain the old transmission fluid using a fluid pump.
Replace the transmission filter and seal.
Refill with the manufacturer's recommended transmission fluid to the proper level.
