My dad's got an Omega 1.8 - not the same car or engine I know - but
prone
to
stalling. The idle control valve gets gummed up and sticks. A common
problem
on Vauxhalls.
I cleaned his out with carb cleaner, plus vauxhall did a mod on the 1.8
to
add an oil seperator in the breather. It's been fine since.
At one year old though the dealer should be able to sort it.
be interested to know what the fix is.

Hi

They have said it needs a new vaporiser. They say there is a
sensor/electronic problem and as they are sealed units it needs replacing.

Hi

An update. Vauxhall dealer fitted new vaporiser, apparently this didn't
seem to fix the problem, so they fitted new spark plugs. It seemed better
on first driving it, but has started to exhibit the same sort of problem
within a few miles. On stopping (clutch down) the engine gets close to
stalling before jumping back up to normal tick over, when driving on petrol
it is fine. There doesn't seem to be any particular pattern, sometimes it
is okay when I stop other times it struggles. It is as though when I take
my foot of the accelerator the gas flow is stopping completely for a split
second and so the engine starts to die then it recovers.

Before going in to be looked at the car had stalled a total of 4 times, one
of those was when I just changed gear and so I effectively bump started it
as the clutch came up! It has hovered around stalling point many times,
very annoying, and still seems to be the same after being fixed. Guess it
will have to go back again.

Is the Idle control valve in the vaporiser?

Maybe the idle speed is just a ;little too low for gas. See if you can
raise it at all, just a mere 30rpm can make a big difference
