So I have a 2015 Lariat, 3.5L ecoboost. Been very problematic. Currently, I always get a check engine line and P0234 code under very heavy acceleration. Every day when I merge onto the expressway on the way to and from work. Is this a wastegate issue or a BOB issue? If it is a wastegate issue, is it the actuator and can it be replaced? Any help is appreciated. Thank you!
