307 LPG and Gas Stop Problem

I have the 2005 model 1.4 XR 307. I have a problem with stopping after speed fluctuation while idling. It stops especially when I turn the steering wheel or fall idle to the road. I cleaned the throttle throat, renewed the version of the ECU, so I did not do it, but the problem was not solved. I suspect the latest Lamda (Oxygen) Sensor malfunction. As a motor teacher, I can't solve the problem. I would appreciate if you contribute in this matter.

What is the Brand of the LPG You Have Taken?

this is the most common idle valve malfunction. have you checked it?

I had the same problem. However, they adjusted the LPG again and the problem of stopping was resolved. However, the ripple problem persists when the engine is cold. No problem when the engine gets hot. I have read in several places that the butterfly should be adapted with gas after cleaning. Is it necessary to do such a procedure?

Hodja, I wonder what the result was
