    Have you had any problems at all before now?
    You can (and I think will) rule out the catalytic converters being plugged by removing the two forward O2 sensors. That would give any exhaust back pressure a route to escape (the holes where the O2 sensors used to be).

    Edit: Checked your history. Not looking good...

    Yeah, it was the other problems that can lead to this that I was concerned about.
