Got my new intercooler installed today, but now im having problems. On the way home from the dealer my Service Engine light came on and now the truck idles rough, also it whistles really bad when you shut the truck off, like there is a leak somewhere near the supercharger. Has anyone had a problem like this or knows what it could be?

 

I don't know how it is, it just is. It seems like once the dealer opens up a component, the one problem you had is now multiplied by at least 2. At least in my experience with the boneheads where I live. I dread the day mine starts leaking. I may just buy the parts and do it myself. Sad, sad, sad.

It sounds like a gasket isn't sealing correctly causing a vacuum leak. Probably a major one since you can hear it whistle. Did I mention I hate them? How do they do this over and over again?
