Hello, what is the model and engine size? Or just post the VIN and we can look it up by that. There are quite a few V8s listed, post the 8th VIN as well.

This is for VIN (8th digit) N and Z. Here is a guide for finding vacuum leaks as well, I prefer to use a smoke machine, but you can use carb clean or even water, The water test does use flammable liquids, but you will hear it being pulled into the intake where ever the leak is. Sounds like it's a pretty big vacuum leak. I would suspect the intake gasket as well.
