[QUOTE="Patrick Feeley, post: 1508082, member: 2142"] Hopefully its been serviced with the Royal Purple oil rated for a diesel! These HEUI-based diesels are pretty finicky on the oil. As Magnum PD mentioned you could try a new CPS for the jumpy idle, but use only a genuine OEM Motorcraft or International part. You might need to [B][U]physically[/U][/B] remove the chip (keys not in the ignition!!!) and see if the idle problem changes. Note that this is not the same as putting the chip in stock tune. The "cutout" when you let off the gas and coast is pretty much normal for these trucks (nothing wrong there). Cheers! [/QUOTE]
