I couldn't go above 10mph so I knocked out my clogged catalytic converter and now sometimes it will barely take off it will bog down real bad. But if u floor it it falls on its face need help badly

You very well may have a chunk of the converter floating around in your exhaust system somewhere. Did you remove everything from the cat or just bore a hole thru it. A loose chunk can cause an intermittent issue. Check the muffler and pipe between the two.
