Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Disconnect the battery to avoid electrical hazards.

2. Inspect and Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the air filter and inspect it for dirt or damage.
Replace with a new air filter if necessary.
Reassemble the air filter housing.

3. Check Fuel System

Connect a fuel pressure gauge to the fuel rail.
Start the engine and observe the pressure reading; it should match manufacturer specifications.
If pressure is low, check the fuel pump and replace if faulty.
Replace the fuel filter if it hasn’t been changed recently.

4. Inspect and Replace Spark Plugs

Remove the ignition coils using a socket set.
Extract the spark plugs with a spark plug socket.
Inspect for wear or damage; replace if necessary with OEM parts.
Reinstall the spark plugs and ignition coils.

5. Transmission Fluid Inspection

Locate the transmission dipstick and remove it.
Check the fluid level; add fluid if low.
Inspect the fluid condition; if it appears dark or burnt, consider a transmission fluid change.

6. Clean Throttle Body

Remove the air intake duct connected to the throttle body.
Use throttle body cleaner and a soft cloth to clean the interior surfaces.
Reassemble the intake duct.
