I've had the IAT after cleaning (have no idea what I did) I had moosing. Had never had it before 98 Mystique LS bought new 08/97. So it has all the revised intake tuning hoses/pipes.
Removed IAT again - cleaned it very carefully reseated the hoses- PFM or as we use to say at the phone company CCWSA (came clear while scratching). Yes this is a very touchy area.
I do have the secondary IMRC throttle stop opened 3/4 turn.
We use to call that something??? cracking the ????. If anything I thought that made it less susceptible.
