Check your intake and exhaust modules. I have a 1987 D21 and had the same problem (if I understand your post). I replaced the modules located behind the driver side headlights and it fixed the problem. Good luck! I hope this helps.

Check your fuel pressure, and or injectors. You may have too much fuel getting into the engine causing it to burn rich and overheat the converters.

SOURCE: my jetta will start but

Its a computer controlled motor so yes if one thing gives it a bad reading the cpu will try to counter the issue and give to much gas or not the right amount of air to the intake... Just from what i have happen to me I would look for a leaking vaccume line or a clogged cataltic converter befor replaceing the sensors both can give a false o2 reading on the computer and seem to be more common on most cars..

I have a 2000 Chevy Tahoe that did the same thing. I changed the oil pump, new oil, and head gasket. It now has power and doesn't fall on its face when I step into the throttle hard. Hope this helps.

Replace just the TPS Sensor (throttle position),
not the entire throttle body, as you may have been told
