Ryan,

Did this happen all at once? When you replaced the components, are you sure no vacuum lines or sensors were left disconnected?

Since there are no codes and it has a loss of power, the first thing I suspect is you may have a catalytic converter that is partially plugged. When you drive the vehicle, are there any odd sounds from the exhaust? Do you ever notice a rattling from the exhaust?

Take a look through this link and let me know your thoughts:

Let me know.
