Ya gotta know the design before anything. There is a big difference between the 6.9/7.3 IDI and the 7.3 powerstroke. The powerstroke was direct inject and electronically controlled. Started better, ran better, faster, more power, more reliability. The older engines were indirect inject (IDI) started harder, didn't have the power or the speed to them that the direct inject engines had. The 7.3 IDI is just a 6.9 IDI bored out. The 6.9 was actually a slightly better engine in some regards because it had the thicker cylinder walls that were less prone to cavitation issues if the owner didn't use the SCA/DCA/anti-freeze treatment. Some of the IDI's came with a nylon gear to drive the injection pump, chances are this has been changed by now because they would fail quite often.
But as far as problems go, other than the lack of speed, keep your glow plugs, batteries, and filters good, keep an eye on your SCA and you should never really have a problem with it.
