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.

theres always one on the intake manifold working its way down to catalytic convertor is the oxygen sensor 1 heater circuit(pre cat conv) signal while terminal #25 is oxygen sensor 2 heater circuit (post cat conv)

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..
