Many times the problem is a valve cover gasket(s) that has leaked oil onto the hot exhaust manifold underneath it. When you have stopped in traffic, or if you are on a hill, etc., the oil that has leaked has a chance to run down on the hot manifold and smells like rubber or oil burning. Most of the time this is just a nuisance but it should be repaired if is bad enough to the point you can smell it in your car or truck.
