Q: Car will not stay running

asked by on August 02, 2017

My husband said the engine started to knock then shut down and when he went to start it again it would not crack over and then started to smoke... Then when it did crack over the car would not stay on. No check engine light came on or anything. He just put oil and all other fluids in a day ago.
My car has an automatic transmission.
