I have had the vehicle into the shop they had it for 1 week and told me they couldn't find anything. They didn't say this is normal. Is it normal? I love my vehicle and don't want to trade but don't want to breakdown either. Anyone have answers please

Directed injected motors do produce soot to some extent. Its not like a diesel but I have been following my wife while she drives my truck and occasionally see a small puff.

If you are driving down the road and there is a visible trail of soot then that would be an issue.

Normal and WAD (Working As Designed).

At startup the PCM automagically increases fuel mixture/ratio until the predetermined warm-up temp' is achieved. *In the old days this amounted to choking the carb'.

its normal, my 2012 platinum 3.5 eco is the same way, use your remote start and start the truck and and you can see the black smoke when it starts up and when its warming up.
