hi all need some advise please car keeps cutting out, today i drove for 5mins come to roundabout and it cut out  it wouldnt restart had to get a jump start from nice man in a van i dont understand why this happends checked clean  battery term, checked earth strap i have no battery light on dash when driving so i know its not alternator it doesnt do this all the time some times theres charge in the battery to restart if it cuts out , theres enough fuel any ideas

Something seems to be draining the battery, and although you state it is not the alternator, it really does sound as though it could be.  Power is draining away whilst you are driving, and if the alternator is functioning correctly that should not happen.  The only time draining power happened to me, with the engine cutting out, was when my alternator packed up.

Does the radio die before the car comes to a halt?

Not necessarily true. Have you checked the alt. output http://www.omegaowners.com/forum/YaBB.pl?num=1225724099
With the Omega strange things are known to manifest themselves if you have a dodgy alternator  :-?

.................in addition always allow for the possibility that the alternator warning bulb has blown / been removed and may not show!

radio is on before car cuts out sometimes i lose radio and have to enter radio code when restarting and other times its okay

Yep a classic sign of losing electrical power from alternator, with the battery drained right out, so no means of running radio.  It just dies, as will all electrical equipment!

PS In the 'old days; we always checked the drive belt tightness on the generator / alternator to ensure there was no 'slippage' thus reducing the power going into the engine / battery.  Worth a check?

start it then take the positive wire off the battery breifly if it stops alternator dead

found out why its cutting out yes battery is knackered also the cutting out is the idle air control valve is sticking when you remove the black plug/clip car still should be running buts its not i adjusted the revs pulled plug/clip off and it was still running so ive been told the idle air valve so i think there about £40 of ebay i think anybody know anywhere were they are cheap apart from ebay

Check out the maintenance guides.

Remove and clean all the breathers, throttle body and idle valve....no need to replace anything other than a few gaskets.

What do you mean when you said you adjusted the revs? Have you been playing with the throttle stop screw??

That takes me back to those fun days adjusting carburetors!!

I feel really at home now! 8-) 8-)

no a friend of mine who used to work for vauxhall did not me never i wouldnt know were to look

Throttle stop screw should not be adjusted....ever....even by someone who used to work for Vauxhall.

The throttle has to close completely so that all the idle air passes through the idle control valve.
To re-set this you have to remove the throttle body, clean the throttle disk thoroughly then set the screw so that the throttle shuts completely without sticking in the bore.

Re assemble then fix the original problem which was probably a gummed-up idle control valve due to blocked breather system.
