Where does this vacuum line go and would the fact that it is not attached cause a CEL to come on? I recently installed a defective MBC (Ebay piece of junk), this required me to unhook the SBC and then the CEL light came on. Is this normal to get a CEL with a MBC? In any case I was having problems with the MBC so I hooked the SBC back up and the CEL stayed. I figured that maybe the CEL will stay until I drive it around a bit but I have put several hundreds miles on it and the CEL is still on. I have already ordered an OBDII bluetooth adapter and plan on checking the code but I found this loose vacuum line and I am wondering if it is the problem. It looks like it comes through the firewall right about where the glove box would be. Where does it go? And can it be my CEL problem?
