My 318 when running down the road, I will let off the gas and the engine will lope and shut off. How can I correct this?

This can be a vacuum leak, a bad IAC valve or the EGR valve sticking open. Please go over this guide which should help us fix it:

Here is the vacuum leak guide, use only when the engine is cold:
