On certain vehicles, the pulse air reed valve (which permits flow of air from the air cleaner to the exhaust manifold) can fail in cold temperatures, resulting in a backflow of exhaust gas into the air cleaner and fuel induction system that causes a rich air/fuel mixture. This condition could ultimately result in spark plug misfire, or engine stalling.
