if you have the eco tec engine it will almost certenly be the idle control valve, it's a common problem and easily fixed by removing it and cleaning it with carb cleaner or such like hope this helps delboy
Possibly a stuck or sticking EGR valve.
There are a few benefits to Vauxhall car insurance. The singularly most important reason to get this car insurance is the low price but alternatively low coverage.

Your engine produces torque(turning power) and revs, and these are related. You can't get more than a certain amount of torque out of the engine at a given number of revs. If you hit a slope in the wrong gear/at the wrong speed, then forcing the car forward will require more torque than the engine can deliver, and it will stall. It's very much like trying to ride a bike uphill in the wrong gear.
generally , two strokes are smaller capacity , shorter stroke, higher revs. for given engine capacity , long stroke /small bore = high torque / low revs short stroke/big bore = low torque / high revs
The idle is set too low or there is an electrical problem
check for vacuum leak or dirty fuel filter
Battery fails to charge, alt light comes on, sometimes only at low revs. Check with meter shows low or no charging voltage (close to or less than battery voltage) voltage does not increase to charging volts with engine revs increase
It means engine coolant is low
The shift light on a Vauxhall Corsa is a light that indicates whether or not you're driving in low gear. It is typically located right on the dash.
maybe rev limeter is set to low????
well that happens to me an it means fuel is low
