After driving my car's rpm go down to 1k while its still rolling. Is this normal?

 

Need more info.

 

after any kind of driving while my car is still moving not in gear. 60-40-20 mph the rpms sit at 1200 to 1k. It just all of a sudden started dropping that low

 

so is this normal.

 

are you trying to say if you put in in neutral at high speeds ( im thinking its a M6) it goes to 1200 to 1k RPM???? if so yes it goes back to the resting RPM's

 

lock-up, non lockup? A4? M6? I had a related issue but the opposite. I have a non-lockup th350 and the RPM's used to drop almost instantly to idle (if I let off the throttle while cruising). Now after a new tune, they sort of hover when I let off the throttle (around 1,200 rpms or so). It sounded badass before, camshafting while doing 60mph

 

yes its an m6 and yes its when i put it in neutral and its at all speeds and it just all of a sudden started doing it is why i was worried about it. it would usually go back to around 1500 to 1800

 

Mine does that all the time coasting outta gear or with the clutch pushed in.
