the car drove fine last night, when I left for work this morning it was 5 degrees below zero, upon putting it in to gear it pulls hard until it starts moving and then it goes into neutral for all gears even reverse until I key off , let the ECM reset and restart. then the situation happens again, also noted a noticeable whine this morning
