I meant the plate holding it down I can't get off, I'll get it, thanks for all your help!

 

Yeah my plug has backed out a little twice. It really throws a fit when this happens. That little yellow plastic plug supposed to keep that from happening. I guess I didn't have it in good.I guess they do go bad though. Good luck. You will get it.

 

I can't find anything on the internet to answer this question but is it normal for the sensor itself to be able to be rotated side to side under the plate that's holding it in since there is no mounting hardware? That's what mine is doing and I would think that would cause a vacuum leak and that's my problem?

 

Mine will move a little too but it is not causing a problem. There is a rubber o ring I believe that seals it.

 

Ok thanks again for all your help, gonna replace it and see what happens.
