My 2011 impreza 2.5i was driving really rough and while driving one day all warning lights came on and a horrible metal on metal noise started coming from engine area. Long story short ended up getting a 2006 2.5 engine and swapping it over. Come to find out the shop that did it decided to just drop the entire 06 engine in I stead of using the 11 intake and heads. Everything was fine at first then I noticed cooling fans weren't working. Ended up swapping the 2011 intake and wire harness along with new coil pack and new sparks and plugs. Now fans working but theres a misfire in cylinder 1. Please help.
