If it was a bulb wouldn't the signal not work on one side? I thought that when I had a blown bulb in my Nova it would not blink on that side and the light on the dash just lite up.
If you swap the emergency flasher for the turn signal flasher and nothing changes on either circuit, it's definitely not the flashers. For the bulbs to be working OK and the flasher to operate too fast, there must be some additional current draw on the turn signal line when it is activated. This didn't begin right after your changed some bulbs, did it? If so, make sure you installed the correct bulb number. Otherwise, check for some [partial] shorts in the turn signal circuit. Maybe a chaffed wire somewhere....
