Solution

1. Preparation

Gather tools and parts needed.
Disconnect the battery to ensure safety while working on electrical components.

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 and debris.
Replace with a new air filter if it appears clogged.
Reassemble the air filter housing cover and reconnect the battery.

3. Fuel System Inspection

Connect a fuel pressure gauge to the fuel rail.
Turn the ignition key to the "ON" position (do not start) and check the pressure reading.
If the pressure is below specifications, inspect the fuel pump and fuel filter.
Replace any faulty components.

4. Throttle Body Cleaning

Disconnect the throttle body electrical connector and throttle body intake duct.
Remove the throttle body from the intake manifold using a socket set.
Clean the throttle body with throttle body cleaner and a lint-free cloth.
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.
Inspect for wear, carbon buildup, or damage.
Replace with new spark plugs if necessary, ensuring proper gap settings.
Inspect ignition coils for any visible cracks or signs of wear and replace if needed.

6. Transmission Fluid Check

Locate the transmission dipstick and remove it.
Check the fluid level and condition (should be red and clean).
If low, top up with the recommended transmission fluid type, ensuring proper fluid level.
