THank you now just gota go to the parts store get some new hose

Based on your response I probably should be but I am not. I havnt really looked closely at anything on the 4.9 that I have, but I did notice that it has an egr and some other smaller vaccum tubes, just thought it would be nice to have a reference.

What am I missing here?

have you checked any cadillac forums?

Off the back of the EGR solenoid there is a port and had a hose hooked to it where dose that go on the 2.8 V6 and thaks for all the help

The fresh air port on the back of the solenoid is suppose to have a hose that goes to this metal line on the firewall.

3800 series 2 Vacuum line Diagram? would be a gigantic help! !!! ! !
