My factory iat sensor on my 2.2l plugs into a rubber grommet . did a boost leak test and I thought that the gromet was my issue so I moved the sensor with a new grommet only to find out that it was the sensor itself leaking. If I put it to my mouth I can blow threw it in both directions. I had another one laying around that did the same thing. Has anyone else seen this? Is this normal on these ?
