I purchased a new F150 ecoboost 2 months ago I was averaging 15-16 city and 18 highway. around 700 mile on it i got a check engine light on it took the dealer 400 miles till they took it in the code was for an engine overboost, the dealer said the solenoid for the turbo waste gate was burned up, since I got it back my fuel MPG's has decreased to 12-13 city and 16 Highway. I now have 2400 miles on the truck has anyone had a similar issue?
