I need to change the egr valve in a 97 deville . I'm mechanicaly inclined after exposing the fuel rail and removing the 4 bolts . Am I just to lift up on the whole assembly rail with injectors ? All the way off ? Do you have to depressurize the fuel rail ? Then remove valve and install new one . Push back rail injector assembly ?

Let's move this question from the Tech Tips forum (Do it this way) to the Engines, Northstar (How do I fix it) forum.
Spotman, Please use the Settings and My Profile tabs (upper right corner) to update your profile. Are you really 74 years old (birth date) and live in London (time zone) ??? Please read each forum title banner to find out what is supposed to be posted there. Thanks for the interest in CF.
If you can wiggle the EGR valve out without disconnecting the fuel rail, then there is no need to depressurize it, but if you have to disconnect, and I suspect you do, it will have to be depressurized.
It should have the stainless steel fuel rail.

I did mine on my ETC and I did not have to disconnect.
I assume the Deville would be the same, but not sure.
