5.0 coyote Engine smokes running fat with fuel plugs have oil and fuel

[Dbrd_5.0]

Hey guys I'm I've been looking around some forums for some help. I have a 2011 5.0 coyote. And I had a email tune from Lund racing uploaded to he car. It didn't run everyday because it needs to be data logged or fine tuned, my laptop broke, so I've been waiting to get my new laptop & the car has been parked... But even though The car is smoking and running hell of rich or fat, I pulled the plugs and there is some oil or bit of carbon on them and they smell like fuel running 98 octane. About to get the car tuned 100% anybody know what could possibly be going on.

you say the car is smoking, what color is it? Did it start right after the tune?

if the plugs are wet and oily, you may have a leaking valve cover gasket.

Its probably on the rich side, putting out black smoke. Probably from a tuning standpoint, to have extra fuel on the base map and dial it in off of the logs. Just a guess

White smoke, not right after it was about I'd say a week or so. I haven't bothered messing with the car, I had to do some work on my 05 3v GT. So now I'm about to start on the 5.0

White smoke after sitting is probably condensation.
Most likely cause of the sooty Or blackened plugs is from a fat fuel tune .

White smoke, oil on the plugs....sounds like one of the old #8 failures.

Lund has been tuning 5.0 for a long time, you wouldn't think the tune would be that far off.

Yeah that's what I've been hearing a lot so far. I'm hoping once I get it tuned it should be ok
