been down 2 months due to BSD issue. car is good now. seeing throttle closures.

Found that after releasing throttle there was a good size puff of smoke out of the exhaust, noticed on start up the engine is running rough and then smooths out saw that when this is happening the engine is running very lean, also having a check engine light for a lean condition. While I’m driving I saw that my afr is good under load and boost but was sitting about 15-17
