NZ new 2009 model. Find the Acceleration/Throttle is rough. Also occasional unstable/fluctuating RPM at idling. Had an engine cut-off for first time this morning while stationery at traffic lights ( on D and brakes) - after fluctuating RPM.
Issues seem more profound after battery change a few weeks back. Please advise.

Hi there,
There are a lot of possibilities, so I recommend talking the car to a workshop for a diagnosis.
You may just need the idle memory relearning after the battery replacement.

Okay noted. Thank you.
