It does have some play in it. It's clipped into the port by a plastic clip and it has an orange rubber seal that seals it. I had my intake off this weekend putting heads on and I took that sensor out of the intake to look at it. I noticed it's not a real tight connection. There is also a vacuum port right under that sensor. Check that connection and follow the hose down to the tee where it splits off, that could be a problem too.
