Hi, I recently put a 2013 forte engine in my 2010 forte. When we went to switch everything over the only thing the 2013 didn't have was the exhaust valve control solenoid, In fact the place where it would go (the back side of the head) on the 2013 wasn't even there. Now my CEL light is on, is there not a EVC solenoid on the 2013 2.0L? Thanks!
