I have a 2003 Mercury Sable. There is a burning smell/fumes whenever I am stopped at a light or put the car in park. The smell comes from the drivers side but I don’t smell anything when I am moving. Any ideas on what could be causing this?
The next time you get the smell when getting home, with the engine idling, open the hood and check to see if there’s smoke being created from something dripping on a hot engine component.
Time for new valve cover gaskets, my guess, not too expensive but the problem should be verified before any work takes place.
