Title: What is causing this?
Post by: zuluf on 30 November 2010, 22:35:06

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

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)
