I am a very comfused individual now. I drive a 1999 Mercury Mystique GS. The engine is the exact same as my friends ZX2, which is thought to be a Zetec engine. However neither one of us has Zetec printed on the engine. Also I have never heard of anyone talking about a VCT engine on these forums. So I'm confused. Is it Zetec or what? A stupid question that most of you will laugh at but I have to know.
