No codes. I'm not sure about the IMRC. It is a 2000 SVT w/94,000 miles on it. I did notice the nice little box fan light came on briefly the other night but hasn't returned.

Excuse the ignorance on this question. What is the hose that runs down from the intake and goes next to the IMRC? Is that part of the IMRC? I've noticed cracking on it and have wondered if this is a contributing factor.
