Solution

1. Preparation

Gather necessary tools: OBD-II scanner, fuel pressure gauge, socket set, torque wrench, cleaning supplies.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Clean Air Filter

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

3. Check and Repair Fuel System

Connect the fuel pressure gauge to the fuel rail.
Turn the ignition to the "ON" position (do not start the engine) to check pressure.
Compare the reading with manufacturer specifications; if low, check for fuel pump issues or clogged filters.
Replace the fuel filter if it is clogged; if the pump is faulty, replace it as well.

4. Clean Throttle Body

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 body and remove carbon buildup.
Ensure the throttle plate moves freely after cleaning.
Reinstall the intake duct securely.

5. Inspect and Replace Ignition Components

Remove the ignition coils using a socket set.
Inspect spark plugs for wear or damage; replace if necessary.
Check ignition coils for proper operation; replace any faulty coils.
Reassemble the ignition system components.

6. Transmission Fluid Check and Replacement

Locate the transmission dipstick and check the fluid level and condition.
If the fluid is low or discolored, drain and replace with manufacturer-recommended fluid.
Use a torque wrench to tighten the transmission pan bolts according to specifications.
