Idling was hunting so I changed fuel pump and MAF sensor then the car was fine for 2 weeks then it started idling hunting again. Got another MAF sensor but nothing changed, it's moving but it won't go over 100KM/hr.

Hi,

Have you checked for diagnostic trouble codes? Have you checked for engine vacuum leaks which can cause an idle issue? Also, this model isn't offered in the US, so my technical info is limited. However, the vehicle should have an idle air control valve. It would be located on the throttle body. Check that as well. It may need cleaned. Here are two links you may find helpful:

Let me know if there are any symptoms such as engine temperature is high or low, smoke from the exhaust, smells or anything you can think of.

Take care,
Joe
