I've got a 2013 ecoboost the truck seems to go into limp mode and throws a P0299 code. If I shut the truck off and start back up it runs "normal" again. I've changed the actuator on the left side turbo. It seems like a vacuum issue, but not sure. Can it be the turbo itself? The fact that I can shut off and restart and it works makes it confusing. Thanks in advance.
