Scotty,
I have a 2013 Cadillac ATS with a 2.0l turbo and 88,000 miles. I've been getting a P0171 running too lean code. I changed the mass air flow and checked for vacuum leaks, couldn't find any. Took it to a local mechanic with a good reputation. They said it's the boost sensor, can that be correct? The engine is misfiring and is sluggish at times.

Well if it's boosting wrong it could be running lean because it could have had too much air to the system a turbocharger throws air into the engine if you get too much air that makes it run lean
Thanks Scotty, I really appreciate it.
