My first car was a 1991 Talon and I had the same exact problem. The car ran fine at idle but as soon as I went over like 2800rpm the car would bog down really bad and loose most of its power. I couldn't figure it out for the life of me, so I took it to my local mechanic, he threw it on the computer, and it turned out to be an electrical problem and the car was only firing on 3 cylinders. I can't recall the exact problem but $800 later it was fixed. You might want to get it checked out by a shop.
