what want me do ？ where want me go ?

正确的疑问句要有疑问词和助动词、主语等构成，你这句就没有助动词了，也没有了主语。正确的说法是：what (do you) want me to do/go？并且want后面因接to做不定式

我不知道你想说什么？
如果你想说：我想要做什么？我想要去哪？就是：What do I want to do? Where do I want to go?

如果你想说：你想让我做什么？你想让我去哪？就是：what do you want me to do? where do you want me to go?

不对！

what do you want me to do?

where do you want me to go?

缺少to。
to do
to go
