Most common reason that you will have heat when driving and not at idle is that there is an air pocket in the cooling system. This can be caused by a leak in the system. I would recommend that you have this checked out immediately. An air pocket in a cooling system can cause a large amount of damage if it's not caught early. Best of luck
