I have a 99 Ford Ranger. When I am idling at a light with my air on and other cars are around me I smell exhaust. I do not smell it if there are no other cars around. It gets so strong that I have to turn my air off. It just started doing this a few weeks ago. I have never had this problem before and I bought the truck new. What could this be? Thanks
