Adamw Posted April 5, 2019 Report Share Posted April 5, 2019 It would have helped to know which model impreza we are talking about. Im assuming it's a V10 as that is the only one with an ANV5 connected to anything important. On the V10, ANV5 is the RH tumble generator valve position and could definitely affect the way it runs. If its running rich it suggests the valve is stuck closed. Quote Link to comment Share on other sites More sharing options...
