If you disconnect the intake piping from the CAC, then idle it, does it stop the problem?.

Also, if it was done 4 years ago, you will want to get a program update at some point in the near future too. A lot has changed since then. Pulling a copy of the program out of it and e-mailing it to me, I can inspect and update it.

I'll have to check and see if disconnecting the intake piping makes it stop or not and get back to you. Same on pulling a copy of the tune. It'll be this weekend before I'm back around that truck. Appreciate the guidance Rawze.
