Recently purchased a pre owned Nissan Titan and brought it in for service, told the technician about the problem in the engine and he said that because there is no light on that there isn't anything wrong with my truck. As soon as I drove off the lot again the problem still existed. And still exists. I think it's very unprofessional for a mechanic to overlook a problem because a computer doesn't indicate there being one. When I personally told him what was happening. Are Nissas mechanics taught that if the computer doesn't show that there's a problem then there isn't one? Because that's ridiculous. Thanks
