Problem with the minimum
Hello everyone, I write from Rome. I have a 245 Super Polar from 92 with B200F engine. For some time now I have the problem that you can see in the attached video
https://www.unpodicose.it/fileweb/problem.mp4 If I unplug and reattach the battery, the problem no longer does but then resumes. The control unit reports errors 2-1-2 and 2-3-2. The problem does it both on petrol and on LPG. Sometimes LPG goes at 2000 rpm, standing still. Thanks for your help.

First thing I would do is a smoke test and check for any air leaks

Error code 2-1-2 is a faulty oxygen sensor signal, 2-3-2 is fuel system compensating for rich or lean mixture at idling.
Fit a new oxygen sensor? |

Sorry, I'm not clear. Do you mean this fault has started since you fitted the new sensor, or do you mean the fault was there before but the new sensor has not cured it?

Sorry, I'm the one who wasn't clear but I don't speak English.
I bought it yesterday. I wait for it to arrive and then mount it.

have you tested the output from the sensor?
I doubt it is the issue but there is a small chance it could be |

A simple test would be to reset teh ECU and disconnect the lambda signal wire
