    Double check that you dont have any exhaust leaks, Iv heard that the gaskets need to be replaced otherwise ull have Somthing like a flat spot. Just a suggestion.

    Does it do it at specific speeds?

    Like most cats with 280,000k's on them, they will be blocked to a certain degree.

    I'd check the fuel filter and fuel pump. A partially blocked cat will still rev, just won't be as quick to get there.

    Sounds like a fuel issue, have you cleaned the injectors?
