Is it STILL putting out cloud from tailpipes @ WOT?
If so, it is getting one of these pulled into the cylinders @ WOT (1) Oil, (2) Coolant, or (3) too much Fuel. Of course, it is also possible that the "smoke" is from intermittent spark without injector shutdown.
I would suggest:
1) Clear all codes (after recording code numbers & Freeze Frame Data);
2) Retest. You should use DS and manually shift to see if you get an SES light or Tailpipe "Smoke" at higher RPM (~ 5,000 RPM) in 2nd or 3rd, WITHOUT high LOAD or throttle more than ~ 40%. Then when engine warm, do WOT acceleration in 1st & 2nd to see what happens.
3) Let us know what SES or other warning lights you got, and the Fault Codes you now have, along with FF Data and mileage at time of test causing tailpipe "smoke."
4) Let us know what Scan Tool/Diagnostic Software you have available.
BTW, it is significant what COLOR the tailpipe cloud is (black, gray, white), so it would be helpful if you could have a reliable observer follow you and note that.
Please let us know what you find,
George
