Clean check connections to the idle air control valve. Clean the vale itself.

As Wammers says above and as I said in your previous post about LPG and cold starting issue - http://www.landyzone.co.uk/lz/f10/lpg-problems-258452.html - check the ICV....

No there is no problem to idle valve air control.I have cleaned. this problem is caused when is warm or cold when you start the car. The rpm dose not shake in this case, and this happend even in petrol. In fact in petrol because when the car start is in petrol. Could be the spark plug???

When the crankshaft sensor detects load on the engine by reduced RPM the idle air control valve opens to give more air and therefore more RPM to overcome the load. If the engine stalls when load is applied the control valve is not working or the crank sensor is not picking up the change in RPM.
