circulation

My friends are kicking my car in cold weather in LPG. The LPG master said that either the circulation or regulator would be faulty. When the regulator speeds, it becomes extremely cold. So lpg master said there was a problem in the circulation. What kind of a problem can I want to take advantage of the experience before I go to the master? Please help me.

Please help if you have information

Not the circulation, my brother, the circulation only ensures the water cycle, bring your car to the lpg master
And get your lpg brain connected to the computer if it fails to change the circulation degstrn.

Thanks
