The car loses power when going up a hill. When I get up to a desired speed (say 60) and back off on the gas going up a hill it starts to slow down. If I then press on the gas it continues to slow down until it seems to sort of "kick in" and the engine revs and jerks a little and begins to speed up. There is also a sort of hissing noise. By the way, it is a turbo.
