I recently replace my Stock housing on my 2013 2.0t genesis coupe, and it was running fine for a couple of days. The one day I floored it and I heard like something either came apart or fell from the car. Now it’s not running correctly from 0-40 mph it runs great but then trying to get over 40 or to accelerate to get on the highway it takes it’s time to get up to highway speed. Also when is starts it idles weird and I went to go get it checked out but it says I need to replace the O2 sensors and I just that but Im still having the same problem. Anyone have an Idea what else is wrong?
