Just to be clear, there was no issue before you put the converter on it and now all this started?
If so, what was the reason for replacing the converter? Where did you get the converter? Was it new or used?
It sounds like the converter is plugged so we need to explore that.
I would suggest starting with removing the upstream o2 sensors and drive the vehicle to see if the power is a little better. Clearly this is not going to free it up completely but you should see a difference.
Please let us know what you find with this.
