aggrevaton or major problem.
For a little background info, I've had a Ford pickup in my driveway for as long as I can remember, BUT they've all been gas burners, so I'm familar with the trucks, but not diesels. Hence my problem.
I'm looking at purchasing a '94 with a turbo diesel (102k miles) in it. The truck starts right up with no nasty noises and idles fine.....except for an irregular miss. When you speed the engine up, it becomes much less noticabe. Like I said, I know very little about diesels, except they should NOT miss. The owner says that once the engine is up to operating temperature, the miss goes away. I haven't driven the truck yet, so I can't verify this.
So my question is, what could be the cause of the miss. It looks like the water seperator/fuel filter is old, and the owner can't remember the last time he had the injectors cleaned if that's any help. TIA

It is probably an IDI if it doesn't say PowerStroke somewhere under the hood. An easy way to check is to see if it has fuel injector lines going to each cylinder. If so, it is an IDI. There is also a way to check from the VIN, but I don't recall which letter to look for or what it should be.
If it is an IDI it would probably be something with an injector, and with a PSD it could be lots of different things. Most people on this board will say the PSD is better, but I am sure you will get a different opinion if you go over to the IDI board. From the way I understand it, the IDI would be better if you want to burn bio diesel in it.

The miss if probably an injector. There is an old school method of checking which injector is the problem. With the engine idling, briefly crack open the nut on top of each injector one at a time (where the fuel line goes in the top of the injector). The engine will run rough when a good injector nut is loosened, but it will not change much when the bad injector nut is loosened. If you aren't comfortable doing that, you can remove all of the injectors and have them tested at a diesel repair shop.
