throttle body help?

[k-series]

So I notice when my car warms up it starts to have a bouncing idle from 1k-2k. I cleaned iacv and still does it. So I checked the throttle body and notice all the screws were loose so I'm at a lost wondering why are the screws loose. When I tighten them up and try to drive the car it has no power somewhat feels like its running on 3 cylinders. But when I loosen them up car runs fine?? Any clue

Ps: its a b series swap!

Check to see if you have the right throttle body gasket. Or if the gasket is on correctly.

The bolts being tight are causing the butterfly to jam up

So should I get a new throttle body?

I don't think this is the problem.

I'd check the gasket. Maybe something is wrong. And when the throttle body is tight it's jamming up the passage to the map sensor causing the car to run like a subaru. And when it's loose it's getting vacum to the map sensor to read something. That's my input on this. But I don't know.
