Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to ensure safety while working.

2. Clean or 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.
- If dirty, clean it with compressed air or replace it with a new one.
Reassemble the air filter housing cover securely.

3. Fuel System Inspection

Locate the fuel rail and attach the fuel pressure gauge.
Turn the ignition to the "ON" position (do not start the engine) and check the pressure reading.
- If pressure is below specifications, consider replacing the fuel pump or filter.
Once inspected, disconnect the gauge and reinstall any components removed.

4. Throttle Body Cleaning

Remove the intake duct connected to the throttle body using a screwdriver.
Use throttle body cleaner and a soft brush to clean the throttle body and plate.
Reattach the intake duct securely.

5. Transmission Fluid Service

Locate the transmission dipstick and check fluid level and color.
- If low or burnt, drain the transmission fluid using a fluid pump.
- Replace with manufacturer-recommended transmission fluid.
- Recheck fluid levels after running the engine.

6. Spark Plug and Ignition System Check

Remove the spark plug wires or ignition coils for access to the spark plugs.
Inspect the spark plugs for wear, carbon build-up, or damage. Replace if necessary.
Reinstall the spark plugs and reconnect the ignition components.
