exhaust (b) camshaft position actuator circuit

  1. 2014+ Impala Reviews
    My 2014 Impala LS 2.5 shuts off when idling. My mechanic thinks it's the throttle body. I already replaced my Exhaust Camshaft position actuator circuit sensor bank 1 and it's still shuts off when idling. Anyone else having this issue?
