Hey all, quick question, just noticed my iac has a vacuum inlet but i have no line to it ( actually it was melted through). Does anyone know where it comes from? BTW it isnt shown on my vacuum line diagram under the hood...

Thanks all !!

 

IAC doesn't have a vacuum line. Just an electric plug. Some of them have a little vent with a black plastic vent cover to keep crap out.

 

Haha. I was wondering if it was a vent. I guess the vent cap is missing. Thanks!
