Just got a 97 tacoma 3.4, is the egr valve attached to the throttle body? And what should it look like because mine is missing something, there is no filter or top or vacum lines or anything, It also idles high, could this be the problem? there is no check engine or codes.

Egr ?

My 97 3.4 does not have one. It looks like it has been taken off. does it need one? It idles very high 2000-3000 rpm in cold weather, could this be the cause?

I'm not sure what an EGR is, but I do know that every vehicle I have ever driven idles higher in the cold weather, likely due to the fact that it takes longer to warm up. Just a thought.

Please don't start multiple threads on the same subject. I merged your duplicate thread into this one.
