What fuse did they change? Are you sure it wasn't a relay or sensor they changed? You need to check the computer codes and test the fuel pressure. It wouldn't be a clogged catalytic converter if it happens only occasionally but could be a bad O2 sensor, fuel pump or filter, fuel pressure regulator, VSS (vehicle speed sensor), dirty throttle body or bad IAC motor, throttle position sensor, MAF sensor. See there's lots of things to check that's why you need to check the codes and fuel pressure first.

2000 Ford Contour SVT engine idles high (revs) when driving


It sounds like a faulty idle air control valve. The computer uses the valve to control idle speed by regulating the amount of air entering the throttle body. Its possible the motor inside the valve is weak, or the valve is gummed up. I would unplug the valve when base idle is near normal and drive it for a day or two. If the valve is the problem the idle speed should stay in one place. And it should set a trouble code for the valve being disconnected.
