Hello. From what you are explaining it sounds like a timing chain problem. This is a very common issue on this vehicle. It is caused by either the timing chain itself failing, or more commonly it is caused by an issue with the timing chain guides or tensioners failing. The front engine cover would need to be removed to be able to see what is going on. You may have a separate issue with the catalytic converter failing.
