When changing one of my power steering pipes I found a piece of tubing lying in the engine bay. It is about 10" to 12"s long about a 6mm internal diameter and has two 90 degree bends either end sort of shaped like a bicycle handle bar with most of the length being straight. Probably makes no sense but hey someone may have an idea ? (cant give you a picture as Ive thrown it away but car has failed on emissions and wondering if this has anything to do with it).
