I found a part on Autozone's website. It's called a Decelerate Fuel Cut-Off Relay. I was wondering, since I noticed my starts to smoke white after 30 seconds of decel going down hill when I am towing... is this a part I should be looking/testing/replacing as nessisary, or is this just a figment of Autozone's imagination.

Here's one that states that it is for the diesel application....

Going downhill with no throttle makes mine smoke too.
I always figured it was because no fuel = cold cylinder temps = unburnt fuel.
I consider it normal and don't worry.
