You have a GDi and would benefit greatly from using the re-learn.
Here you go
Learning function if GDI engine.
On GDI equipped cars, when the ECu is replaced or the battery is reset (disconnected), an idle
learning function for the ECU will be required
Idle Learning Procedure
1. Start the engine and warm the engine until the coolant temperature reaches 85c or higher.
When the coolant temperature is 85c or higher, you only have to switch the ignition to the
ON position.
2. Turn the Ignition to the LOCK position to stop the engine.
3. After 10 or more seconds, restart the engine.
4. Run the engine at idle for 10 minutes with Transmission in nuetral (P for Auto), air con
and heater off.
5. Stop the engine.
6. Restart the engine and run it at idle for 10 minutes with Transmission in neutral
(P for Auto), air con on at
max cool, fan high speed and windows open.
7. Repeat steps 5 and 6.
Note:
1. When ambient temp is 20c or higher and the air con has been continually operated, step 7
may be omitted.
2. During idle in steps 4 & 6, when engine operation switches from lean operation to
stoichiometric operation,
engine stall can occur. In this case, clean the throttle body (throttle valve) thoroughly
and repeat step 1 and
the subsequent steps.
