I had my car serviced last week and the guy asked if it stalled sometimes.
he said vauxhal to a mod for the ecotec engines.
where you buy a black box with a filter inside and fit it into the front breather pipe and it will stop the crap getting into the idle control.
i bought this and fitted it over it weekend 2 min job
but when i cut the breather pipe it was full of creamy brown stuff which i did my best to remove.
anyone any ideas what this is
