Default 93 Legacy Touring Wagon Hesitates

I don't quite know if "hesitates" is the proper wording for my particular problem, But here goes.

Every now and then, around 30mph 2-3krpm (not sure which gear, 2/3 I'd guess) I will attempt to accelerate, and the car won't respond, infact, the rpm's will drop some, and I'll have to give it more gas to keep it from losing more power, then abruptly the car will raise rpms very quickly (like it should have in the first place) and go. I do not notice the car downshifting before the rpms go back up. Any ideas?

I've had this happen in another car (non-Subaru) and it turned out to be the Throttle Position Sensor. It seems that it had worn a dead spot where the throttle sat at normal cruise speeds. You can probably test this theory with an ohmeter.

Good luck and let us know what you find.

Your injectors might be dirty as well. I had similar problems in my RS. Got the fuel system cleaned out and no more hesistation!

I had this problem in my 93 legacy turbo sedan automatic but I never figured it out. Is it intermittent or every time? Mine was intermittent.

Thanks for the replies, I haven't had a chance to have anyone take any look at it yet. The problem is intermittent. I swear it happens at random, and I cannot reproduce it when I want to. It also makes a sound when this happens now, I'd call it a "knock" since that word has a different meaning to it (I think). But it sounds something like that. The sound happens a few times, then goes away as the rpms jump back up. (usually 2-4 times)
