Car engine off going downhill on D

Get it scanned to find what code was tripped.

With it being an automatic I'm not sure if that damaged anything or not. To me the car is still in gear so the engine is still turning over, I normally leave my vehicle in N when going down hill anyway and use my brakes to slow. However I drive a manual, so I'm not sure if it's the same in an automatic.

Never never shut your engine off while at speed. The steering wheel could lock even if you put it back to run without starting, there is a moment that the wheel IS locked. Also, if engine is still turning you are damaging your catalytic convertor.

I'm curious Htwhlsmug93 why you do that. Leaving it in gear consumes less gas downhill than idling in neutral, and puts excessive wear on your brakes. While going downhill gravity is pushing your engine to turn and used NO fuel, and idling uses fuel

Thanks everybody for your opinions. And that will be the last time I shut the online off while moving!

ok- it's a 20 year old Honda-

I see your point tennisshoes.I was thinking of the cat because it's a '96
