Guess it depends on what exactly it feels like, which we can't tell over the Internet.

I can say that mine was pulsing a bit. It's a lighter, but faster pulse than ABS. if and pulsing is like a runner breathing after a 100 yard sprint 'deep and heavy' then what I was feeling was like a dog panting--rapid and shallow.

Don't know how else to describe it, but it was absolutely due to a failing hydroboost and weak PS pump. My guess was the failing hydroboost put debris into the system and killed the pump. I replaced the pump, the steering gearbox, the hydroboost all at once, and flushed out the lines and PS Cooler. Pulsing pedal went away after that, never touched the ABS stuff
