Alright so this is the weirdest thing. When I rev or blip the throttle and close the throttle completely the RPMs come back down extremely slowly.

To the point where the engine is still engaged and pulling me along without engine braking even when I'm downshifting and trying to slow down.

Picture this: You rev/blip the throttle quickly with the clutch in - now count for 3 FULL seconds and that's how long it takes the RPMS to come down to idle.

So because of this when I'm downshifting, the RPMs stay so high that it keeps driving the motor forward. It feels extremely unpredictable and unsafe.

What in the world is going on here?
 
I think this was a "quick fix" in one of the latest ECU updates, because people were complaining that the engine was dying when they came to a stop. So the ECU sort of "buffers" the RPM drop a bit.

I'm not sure if there's anything you can do about it except maybe put in a complaint with the NHTSA.
