Will an AIS off a 94 2.3L fit on a 96 2.3L? Need an answer asap please! Thanks.

 

I have never heard of that sensor before, but seeing as how they are the same engine I would assume it would work. Wont hurt it to try and find out for sure

 

Not sure what part your asking about, but if you look up the part number at your favorite autoparts store, or online, for both those year/models, if they're the same part number, that'll tell you if they're the same part & can be swapped.

 

There is no idle air sensor. There is however an idle air controller, I am assuming that is what you are referring to. You could try it, but new ones are not that expensive, and assuming the older one isn't also bad, it could still be calibrated differently.
