From my understanding that if you leave a car in gear (manual transmission) and you coast to a stop you vehicle cuts fuel and that crank rides on the momentum of the vehicle. My question is: what RPM must be sustained in order to assure that fuel is cut?

 

As long as your not pressing the gas and your car is still rolling, i assume.

 

Why?

 

Service manual says "idle rpm"

I'd say around 1200.

 

i always did it between 2000 and 3000 rpms...it worked for me...but i dont got a G yet so i wouldnt know but its a pretty good idea to try it on...lol

 

yea, feels like about at 1200 RPM on my car I can feel the injectors kick back in.
