are you able to tell me the name of the piece i need? I tried autozone oriely and nappa auto parts stores. They say that they cant get the piece i need and need to get it through the dealership. Is it called an EGR tube? I called GMC and they say that part is either discontinued or that they are not finding anything that matches what i am telling them. He asked me does the tube connect to the egr valve and I have no idea im not a mechanic myself lol. So can you tell me the exact name of the piece so I can order it, been at it for weeks and still no luck, id hate to have to replace the whole manifold itself just to fix the car.
