that sounds confusing to me...
but it shouldn't be too loose...
I think mine is pretty tight where it sits in the ECU box...then it connects to another pipe going down, which i think you are talking about and yes it's loose because it just slides into the pipe...
but idk how loose you are talking about.
You helped me out already
It's very secure in the ECU box, though a bit loose on the other end, just like you said, so nothing to worry about.
Thanks for checking.
Oh, my CEL does not come on, lucky me
