I forget about this all the time and it popped into my mind earlier today. To best describe my question I bumped into this vid on youtube:

Sometimes I have a similar problem (it revs from around 1k to 1.5k). It revs and then if you pedal it a bit (or drive) stops and engine acts normal. I tried to narrow down the conditions this appears and its difficult. Sometimes it happens on a moisty day (rain, after rain, fog), sometimes it happened during the summer, cases of winter too.
Mechanic told me that my airflow sensor is faulty but I excluded that after a long read out of different stuff but in the end I did not find a clue to what is the cause of that.
It actually is not a problem, it is more a nagging and irritating phenomenon that I would like to remove if possible

Omega B '97 2.0 16v (x20xev) LPG

Thanks in advance

does the problem occur on lpg and petrol ?

Can happen on both. First thought that passed my mind was that it has to do something with LPG but it is not. Few months ago I disassembled the air intake part, checked it, cleaned all the hoses, cleaned the throttle valve (used the guide from the forum) because I thought it had to do something with that but no results. Tough I did not clean very much idle control valve and that thingy on it (pic no.23 on the link here)
