Hi, after driving for a mile or so and usually when exceeding 40mph, the car likes to stall when coming to a stop.
A good rev usually cures this but its becoming dangerous!!
Could someone please help.

Year = 20?
Can you post the correct year so that either I or one of the other moderators can edit it in.
EDIT - ignore that. Just seen your post on another forum and got the required info from there.

Clean the throttle plate and throttle body.
Check the crankcase breathers are free.
Check the EGR valve. If required, blank it off, or, have your engine's software updated (assuming manula transmission) at a Vauxhall garage to disable EGR.

Hi, I have cleaned out the throttle body, and also blanked off the EGR valve but the stalling was still there although in a more abrupt fashion once the EGR was blanked off.
I havent taken the throttle body off the engine but I have given it good clean around the valve. Will taking it off help? Is there more to get at?
Could it be the idle speed valve? where is that located, i cant seem to find it? Thanks.

>>i cant seem to find it?
There's a good reason for that - there isn't one.
Also check for any leaks of manifold vacuum.

Ok. Thanks for your help but it looks like its garage time! I was hoping to repair it myself but it looks like i've hit a brick wall. I'm pretty sure i've cleaned what i can and there are no leaks as far as I can tell.
Why would this only occur after going over 40mph? Its a strange one.

One last thing to check, before getting serious.
Find a (very) quiet flatish road, and drive along at 30 - 40 ish. Keeping your foot absolutely fixed on the throttle; if needs be, hold your other foot underneat the throttle to stabilise it. If you feel the car pulsing, you may have a sluggish lambda sensor.
If you aren't confident to juggle about with your feet like this when driving, please ignore the suggestion.
A sluggish lambda sensor would explain that you have no problems from cold - closed loop operation using the lambda sensor doesn't happen until the exhaust gas warms up. It would also explain the engine not adapting quickly enough to returning to idle.
This is just a possibility - make sure it is the lambda sensor before fitting one.

Yes! The car 'jumps' when its about to happen so I get a warning before a stall. Like small kangaroo jumps. So this is a possibility....
What do I do now...!
