Why is my car engine surging only on hot (above 90) days?

Recently my car, a 96' Subaru, started surging on hot days - say above 90F or so. Usually this happens when the RPMs get above 2000ish. It usually seems most severe in 3rd gear for some reason.
The surging feels like I am pumping the throttle, and the car does this herky-jerky acceleration as I get up to speed. Typically once I get up to 5th gear it smooths out.
Any ideas? My coolant levels seem fine, and oil levels are ok.
