The stalling when driving happens a lot of the time, slightly less when at running temperature. Always under powered. I can make it stall by pushing the throttle up quickly from under the bonnet.

Are you available this morning, I can be there in under an hour?

Thank you for helping out.

I ran the paper clip test. Very simple, even I didn't blow anything up. The only codes were 3x  19 Incorrect RPM Signal. I am not sure if the code is left over from the crank sensor failure 12 months ago so is there any way to clear the codes?

I have noticed it has acquired a high pitched whine on starting that lasts for between 30-60 seconds. This is a new 'feature' along with the irregular idle and stalling.

This could be the SAI pump, located behind the front bumper, on the passanger side (on RHD car).
I have the same sound.
It can be disconected, because it is useless >:(

When you say disconnect the SAI pump do you mean just pull the electrical connector?

Each code gets repeated 3 times so that sounds right for a failing crank sensor.

I think old codes clear themselves after 25 starts so if you changed the crank sensor a year ago the code should have gone by now.

Did you fit a genuine sensor?

Know idea if it is a Vauxhall part but it is definitely a sensor! Got it from Europarts.

Update - Took out the crank sensor and cleaned the oil off. Think the oil is residual from the rocker cover gaskets leaking. That was fixed about the time it started stalling. The sensor lead had been put over the top of the exhaust so I routed through the large gap by the ABS ECU. Make more sense to me because I can now get to connect easier. I have got pictures if anyone is interested.

Went to work and back without stalling. Still under powered and changing down too often but not as bad as it was. Should I get a new sensor or wait and see if the ECU adjusts to the improvement (I've heard they do that)?

New sensor and VX part ONLY ... buy a pattern one and you'll be changing it again very soon.

Guide in the "how to's" on re-routing the cable.

genuine only .. no messing .. :)

Can anyone recommend a good place to get a crankshaft sensor part 90492061 (oval connector) at a reasonable price?

TIA
