Thanks for your replies. I read up on a good shop in the area and had to have my car towed in. It turned out that one ignition coil went bad and was causing the rough idle and loss of power. This workload was too much for the other coil which went and I guess fried the ignition control unit in the process. After having these parts replaced the car runs good except for a slight miss every now and then at idle. Maybe it's just a loose or bad plug wire.
