Smoking at start up
I have an Ecoboost FX4 and I have noticed that my truck smokes (black smoke) for a few seconds after I start it. It also idles a little rough. This all seems to cure itself after it warms up for a minute. Has anyone else noticed similar issues?

Eco-5.0-Eco again
Black smoke = rich mixture...
Check the tubing around the filter/intake tubing, you might find a hose disconnected. I actually had to use a hose clamp to hold this on the connection. Cured my "searching" idle at start-up. Anytime you have unmetered air, it can cause a rich or lean condition...
