"The recall for the valve spring issues, involves vehicles manufactured from January 16, 2012 to May 14, 2013. The affected models are 2013 Model Year (MY) BRZ, 2013-2014MY Legacy/Outback, 2012-2014MY Forester and 2012-2014MY Impreza/XV equipped with the FA20 engine or FB20 engine." Mine is a 2011. Will have it checked tomorrow..

My 2011 Impreza has acceleration hesitation issues if RPM is below 2K. Once it reaches 2K, problem goes away but comes back again when it upshifts and RPM falls below 2K. I've tried cleaning the MAF sensor and relearn throttle position but problem still persists. Any suggestion what to do next?
