Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and set the parking brake.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Clean Air Filter

Remove the air filter housing cover using a socket set.
Take out the air filter and inspect it for dirt or damage.
If dirty, clean the filter with compressed air or replace it with a new one.

3. Fuel Pressure Check

Connect the fuel pressure gauge to the fuel rail.
Turn the ignition to the "ON" position (do not start) and check the pressure reading.
If the pressure is below specifications (consult the service manual), replace the fuel pump or check the fuel filter for clogs.

4. Throttle Body Cleaning

Remove the intake duct connected to the throttle body using a socket set.
Use throttle body cleaner and a soft cloth to clean the throttle plate and housing.
Reassemble the intake duct securely.

5. Transmission Fluid Inspection

Locate the transmission dipstick and remove it.
Check the fluid level and condition (should be bright red and translucent).
If the fluid is low, add the correct type of transmission fluid as specified in the owner's manual. If contaminated, consider a transmission fluid change.

6. Exhaust System Inspection

Visually inspect the exhaust system from the manifold to the tailpipe for any signs of damage or blockages.
If a blockage is found, replace the affected exhaust components.
