3.2 Omega estate just cuts out for a fraction of a second occasionally but sometimes just dies altogether.Won't immediately restart, then will after a short period.Otherwise runs perfectly ok.Any ideas? Problem appears to be worsening.

Suspect camshaft or crankshaft sensor failure.

Hi,
had this problem on my vectra 2 litre SRi, Could be ICV idle contol valve and/or breather pipe, on my vectra, the pipe was coated inside with a bubblegum like substance. I just replaced the breather pipe, that solved the problem!

How old is the car?? Maybe the contents of the cat convertor are breaking up and causing the exhaust to occasionally block.

My mate a work has just had the same fault as this with his 3.0 omega, traced it down to the crankshaft sensor using the cars fault log on the engine management system, I think it was log no 19.

Sorry for the delay, I have seen people on the yahoo Omega group have done this DIY, but I don't think they enjoyed it much.
I seem to recall, you have to rerote the wire of one of the sensors away from the alternator, as it can pick up EMF from the alternator which is what makes the sensor blow.
Never done it myself, as I have a diesel.

Crankshaft sensor, almost certainly....

Thanks to all replies to this one.
Problem now solved. Interrogation of diagnostic plug with paper clip revealed error code 19 which was crankshaft sensor of course. This is situated just below the oil filter at bottom LHS of engine(viwed from driver seat)Removing sensor from engine was fairly easy apart from grovelling on the floor that is. Reaching and removing the cable was another matter. The plug is situated on a holder at the rear of the engine compartment underneath the wiper motor. A bit of prising allows a small hand to reach it and disconnect.We tied a wire to it and dragged it down with the old plug to allow us to pull the new plug up(£48 inc vat del. from Autovaux).This was not too difficult but it was impossible to route it the same way as before as the original was trapped behind some oil pipes. Just had to make sure it was clear of exhaust pipe which is close. Alternator is other side on my engine. A good result-car driving fine again.
Also thanks to my vauxhall mad son in law who obviously should be a Vauxhall mechanic.
