I have a 2012 Ecoboost Flex with 27,000 miles. So yesterday i was leaving the car wash and i had to get on it a bit to get in front of traffic and as i looked in the rear view mirror to see how far i was a head of the cars behind me everyone was slamming on their brakes due to my flex looking like i just flipped the smoke screen switch, no exaggeration this was bad, however it cleared up after about a miles or so down the road. Now i have seen maybe a little to no smoke come out of this thing in the past but noting like this at all. So i drove it all around after the smoking incident and it did not happen again. First thing i thought was one of the turbos went out or i broke a piston. The flex has had a tune on it in the past but it has been on the stock program for a while now. All stock except for that
any input would be greatly appreciated
