I have had a high idle issue for about a week now. Last weekend I started the Beast and it didn't quite catch, ended with what could be called a backfire, but it was very small. Since then I have searched the forums for anything I could find and it appears a vaccum leak is imminent. I have replaced the common problem, the PCV connector (it needed it) but can't seem to see anything else loose or hissing that would cause this.
I start it and it will idle high at about 2000 RPM and slowly reduce to around 1000.

What else could be causing this issue? Does the Plenum need to come off?

Thanks
