Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface with the engine off and cooled down.
Disconnect the battery to prevent electrical shorts.

2. Air Filter Inspection and Replacement

Remove the air filter housing cover using a socket set.
Inspect the air filter for dirt and debris; replace if necessary with a new OEM air filter.
Reassemble the air filter housing cover and tighten the screws to the manufacturer's specifications.

3. Fuel System Inspection

Use a fuel pressure gauge to check the fuel pressure at the fuel rail; compare readings to specifications in the service manual.
If pressure is low, consider replacing the fuel filter and checking the fuel pump operation.
If the fuel filter is clogged, replace it according to the service manual.

4. Throttle Body Cleaning

Disconnect the throttle body electrical connector and intake duct.
Remove the throttle body using a socket set.
Clean the throttle body with throttle body cleaner and a soft cloth, ensuring the throttle plate can move freely.
Reinstall the throttle body and reconnect the electrical connector and intake duct.

5. Ignition System Check

Remove the spark plugs using a spark plug socket and inspect for wear or carbon buildup; replace if necessary.
Test ignition coils with a multimeter, ensuring they meet specified resistance values; replace any faulty coils.
Reinstall spark plugs and coils securely.

6. Transmission Fluid Check

Inspect the transmission fluid level using the dipstick, and add fluid if necessary.
If the fluid is dark or burnt, consider a transmission fluid change.
Follow the manufacturer's guidelines for the type of fluid and change procedure.
