Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to ensure safety during repairs.

2. Inspect and Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the air filter; inspect for dirt and debris.
If dirty, replace with a new OEM air filter.
Reassemble the air filter housing and secure it tightly.

3. Test and Replace Fuel Pump (if necessary)

Connect a fuel pressure gauge to the fuel rail.
Turn the ignition on without starting the engine and check the pressure reading.
- Normal pressure should be in the range specified in the owner's manual.
If pressure is low, proceed to replace the fuel pump:
- Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
- Disconnect the battery and drain the fuel tank.
- Remove the fuel tank and replace the fuel pump assembly.
- Reassemble and reconnect all components.

4. Clean Throttle Body

Remove the throttle body from the intake manifold by unscrewing the mounting bolts.
Use throttle body cleaner and a soft brush to clean the interior surfaces.
Reinstall the throttle body and reconnect all electrical connectors.

5. Check and Replace Spark Plugs

Remove the ignition coils using a socket set.
Extract the spark plugs using a spark plug socket.
Inspect for wear and carbon buildup; replace with new spark plugs if necessary.
Reinstall the ignition coils and ensure they are properly secured.

6. Inspect and Replace Transmission Fluid (if necessary)

Check the transmission fluid level using the dipstick.
If low or dirty, drain the transmission fluid and replace it with the manufacturer-recommended fluid.
Refill to the correct level and check for leaks.
