BHP1973

Hi I've owned my Subaru for about 2.5 years and at first it and rarely it seemed like it would bog out or have no response from acceleration or cruising for a few seconds over time it got worse and I discovered on a sharp/fast right turn it would feel like it was getting no fuel for the last year or less it has been accelerating with inconsistent/broken acceleration and in the last week it has started stalling constantly for about 10 starts then no sign of the problem for a while then starts again I noticed that the battery looked like it was leaking so I got a new one but it didn't help then today got the throttle body cleaned but still does the same thing?
