hey guys I cleaned my TB then had to replace the TBS and IAC bc the idle was going funky. It solved my issue but now around 40mph and certain RPMS, I get a strange whistle coming out. Sounds like the intake. Maybe TB gasket needs to be replaced? I got one just in case.I have a K&N CAI Any thoughts?

 

mine does it.. you have the TB spacer?

 

nope no spacer. I just need time to get back under the hood to pick it apart.
