Vauxhall Corsa C problems!

wildest_jjk · 23 Apr 2012 at 16:42

Hey guys,

My car has been cutting out at random times when I have been driving. It only happens every so often and starts up straight a way, but is of course a real pain.

One thing I have read about is the Idle Control Valve and about cleaning it. However I cannot find anywhere that actually says the location of it on a Corsa C.

Do they exist on this model? I know nothing about cars!

Cheers

EDIT: Or is this now replaced by the EGR valve?

is it diesel?

corsa-c.co.uk or migweb.co.uk is probably your best bet

Thanks for the responses. No petrol

Have seen some of the other things posted on those sites, but nothing really about Corsa C's. Thought I would try my forum first!

Cheers

Anyone?

if it dies when you arent using the accelerator pedal, at junctions n things. then its the ICV. the hole it sits in needs the gunk cleaning out and the icv piston needs cleaning too.
it will be bolted to the throttle body and it might be this type or look similar http://i01.i.aliimg.com/photo/v0/294230099/idle_control_valve.jpg

Fairly sure the Corsa C was fly by wire, in which case it doesn't have one. Can you take a picture?

Thanks for the responses.

As far as I can see it doesn't exist, I have tried searching everywhere on the internet and cannot seem to find anything about them and Corsa C's. I will have another look and take a picture if I have no joy.

Cheers.

I'm sure it's fly by wire. Try cleaning out the throttle body. There is usually a build up of carbon around the butterfly.

Thanks for the response again. I will have a go at that then, but could it be anything to do with the EGR valve?

Cheers

Could be a sensor on its way out, might be the crank shaft sensor. Common on Corsa C's.

Zack101 · 23 Apr 2012 at 20:25

No the EGR valve performs a different function.

zipp0r is pretty much right in the description of the symptoms, the car does basically seem to die only at junctions and when the accelerator pedal is not being used. Could the crank shaft sensor cause this?

At least it clears that up about the EGR valve. From what I read on other websites a lot of people did seem to say the ICV but if the car does not have one then would it be best just to clean the throttle body? Is that a similar thing?

Thanks everyone.

It doesn't sound like a crank sensor problem to me, if that was right it would cut out at any time and be difficult to restart. It doesn't have an icv because the butterfly is controlled by the ecu, so yes it is a similar thing.
The carbon builds up in the throttle body so that when you take your foot off the accelerator the butterfly closes to where it thinks it should be but because it is now smaller it's too much and cuts off too much air which causes the engine to stall before it can react.

wildest_jjk · 23 Apr 2012 at 21:02

Thanks again for the response. So if I clean the throttle body where abouts is this located on my car? How do I clean it?

Cheers!

Zack101 · 23 Apr 2012 at 21:12

Ah, if you don't know where it is, a trip to the garage might be better. However if you feel up to it it's on the intake manifold. Take off the big rubber pipe from the air filter to the manifold and you will see the butterfly, take off that housing. You can clean it with brake cleaner or carb cleaner.

wildest_jjk · 23 Apr 2012 at 21:19

I shall give it ago! Thanks for all of the help. I will let you know how it goes.

Cheers!

The EGR valve can cause this problem and there was a fix on the corsa a while ago. The EGR can stick open when it gets gunked up so when you pull up and the rev's drop the engine is fed hot exhaust gas from the EGR and it can cause it to cut out.

If your cleaning the throttle body I would do the EGR as well as they both Gunk up..

Hi there thanks for the response,

Where abouts is the EGR located on my car? I may as well then by the sound of it!

Thanks again

Depending on your engine...
