I need a pic of the EGR on a 3.1 where you can see the wire colors, or how it's supposed to be on there. Long story short someone took the damn thing apart broke off 2 bolts set them in there and didn't bother replacing them. I took it off to fix it and had to replace the gasket cause it was dust, after tracking down some screws that didn't cost $9 each and finding out GM doesn't make the gasket, I made a gasket, first gasket lasted about a month and a half, everything I've tried after that has blown out I think I must have the solenoids on wrong opening the wrong valves making too much pressure, or the passage is blocked going to check that also.

Edit for passages aren't block, looks like the valves never close, weeee time to buy a new egr.
