My 97 Legacy had the same problem. The cure (after much trouble with the dealer) was replacing the knock sensor.
 
Needless to say, I bought my 2005 Outback 3.0R from a different dealer.

Since I've already changed my nock sensor 2 weeks ago, I'm looking elsewhere... Did your "trouble dealer" do something else or did he tried something else before changing the knock? That could maybe help me troubleshooting the damn car...
 
Thanks

I seem to remember that mounting the sensor on the engine had to be done correctly for proper operation. Details have gone from memory
 
Did you replace the knock sensor yourself or did the dealer do it?

I did it, but the proper way. Anyway, my hesitation problem begun before I changed my knock sensor, and I had a CEL saying the knock was out of range. I changed it, deleted the code, and it hasn't re-appeared during my Montreal-NY city - Montreal trip last week-end... So I am pretty sure that I installed it correctly, still looking for the problem though..!

Now that you have the knock sensor replaced, perhaps it is a good time to reset the ECU/TCU memory so it can relearn your driving habits. If you want to try it, you can easily do it by pulling the battery cable for a while to let the system backup power drain.
