i think that you might be runnin somthing old through the engine depending on the last time that you changed the oil, how much you drive it, and it may not be it but try just lettin idle for a couple of hours (quite a while) too get all that old stuff out, it may not be right but its worth a shot

Glad you found the problem.

And FWIW, when a cat conv is clogged you usually loose power under load, such as going uphilll, etc. Jerking or rough running wouldn't be a typical symptom of that.
