I have purchased a 1989 F250 runs great when cold but as soon as it warms up it feel like it is going to stall when idoling. I drives fine. It almost seems like it is sputtering. I also would like to know if anyone has any pics of this motor. I have noticed that something is missing. All the vaccume lines have been plugged and there is no air cleaner.

Sorry i cant help with a picture, but unless someones removed it or painted over it, there should be a vacum diagram under the hood somewhere, usually on the cover over the fan shroud. Some Chilton/Haynes manuals have diagrams in them, theyre not always correct though. Maybe your local ford dealer could help with a diagram. But before you do alot of other troubleshooting, you need to get those lines reconnected, and maybe you can spot why they were disconnected. The EGR system isnt working if all the lines are unhooked , and can cause driveability problems. You might check it to see if its stuck partially open. They may also have the MAP sensor unhooked.
