That is strange. Does is your idle sporadic almost dies low rpms 400 500?
No but of course I have a 2.5 swap in mine but that intake is off my 2.3 engine that threw the rod.
Do you know a part number. And I can't find a wire that would connect to it.
Again I think that is blank and no wire because that was not used on this engine. As for the low idle do you have a CEL? Even if you not have a CEL have you checked for codes?
Nope. No codes. Runs great besides idle. I'm trying to find replacement and wiring diagram for it but I am not having such luck. Why would they leave a open source for air to get through.
I don't think its open, actually quite sure it not. It is just a what looks to be an opening for some kinda valve but nothing is there. Probably used in many of any other applications that it could be for just not our Mazda's.

If that big hole was open I doubt the car would run.

If it was open, then your engine wouldn't even run or would constanly rev to the moon. It's simply a case of the same mold being used for multiple applications.

I have an '06 Mazda3 with the 2.3....same as you OP...not there. And I didn't take it off, so it was never on.

Have you cleaned the throttle body's bore and plate?
