Hi guys. Anyone experience revs hanging at around 1300 rpm when coasting or when sat in stop start traffic once the car is warm? Revs eventually drop when car is stopped but noticing them hang when coasting and not pressing on the accelerator or when slowly crawling in traffic. 

When did you last check the ATF?

after recently resetting my ECU the auto trans is a lot smoother and the idle revs are lower - may want to try that as an easy first option, something tat can be done at home with a laptop and cable? 

Thanks both. It’s interesting as I approached Subaru and they responded to say it’s programmed to hold revs under certain driving conditions and for exhaust emission control.
