Rattling underneath car sounds like it's dragging a chain link fence.underneath it that gets louder with accelleration. Exhaust smell is very pronounced. Loss of compression. Idling rough.
Seafoam it, it works. rough running and fuel smell is from bad EGR. I tried Seafoam on a 98 Saturn with similar issues that was barley running, now it runs great.

Sounds like you need a new exhaust.
