General rule;

cutting out on idle, clean icv. (can also be on idle at speed obviously)

Cutting out under power, failing to start, constant cranking on the key, intermittent symptoms... crank senosr. Not always backed up by the crank sensor code.


Yours sounds more like icv going by description alone. ...?

Can't do any harm to clean idle control valve. Carb cleaner followed by a light oil.


If it persists, might also be worth checking for metal filings on the crank sensor magnetic end.


As said abs is a seperate un related system to crank sensor fault 19.

Will be having another mooch this weekend when I get time, I know the abs ecu was unrelated it was just another job to sort out on it, thanks for the replys so far guys as Asda says every little helps lol.
Will also check wiring from idle valve, one thing I have been thinking about tho when the AC is gassed up (only lasts a week gotta find where the leak is) it doesn't cut out as rpm is a little higher, dunno if this is at all relevent just thinking out loud.

Is the idle rock steady, or is it hunting slightly?

Rock steady 90% of the time and will just cut out, 10% of the time will have a little splutter then cut out or clears its self revs a little and continues to idle rock steady.

Hello again Andy, just picked up on your point re A/C failure. Are you of the mind that the A/C load could be having an impact on the cutting out issue or a prompt for some discussion re the leak?

If the system has no gas (low pressure), the compressor clutch should disengage the compressor removing demand from the engine (same result as with running in 'eco' mode). You can check if the compressor is running or not by viewing the front pulley (bottom right on the aux drive belt looking from the front). If the centre of the pulley is not spinning the compressor is not running and should not be creating any impact on the engine. 

I've recently resolved my A/C leak issue. Systems can leak in many places but in my case it was a leak at the compressor (the seal in the middle of the compressor body, not the high/low pressure pipe union seals...these were secure). I don't know if this is common for the compressors Vauxhall were fitting at the time but just in case, it may be worth you looking for traces of leaked A/C oil in that area. From a cost point of view, I did the work myself (replaced the compressor) and used CoolCar (Shirley,Solihull) for regas...supportive through the repair process in my experience.

Chris- I have read the thread and don't disagree with what people are saying. However what about MAF failure?  When mine went it was cutting out on a trailing throttle or when you pulled up at a junction.

When my MAF went engine just died.  Started ok but died soon as accelerator touched.  Disconnected MAF - started ok and ran reasonably ok.  All back to normal once new MAF fitted

Just a update guys replaced the maf for a known good one a week or so back and..... still the same, came to replace oil cooler today as there seems to be a leak in that area, found the mating surface on the head to the lower divider had a lot of corrosion on the ns head and had pitted the gasket, so fitted new gaskets cleaned corrosion off head, whacked a new temp sensor in there at the same time and up till now all running ok 
Let's hope it may now be fixed.
