Ok peeps,

My girlfriends 1.2litre injection - 8valve 'R' reg corsa keeps cutting out, whilst driving. Generally before its fully warmed up and then it normally wont start again for a while, if it does start again, the revs are all over the place and the engine management light is on frequently....it cuts out as you come up to junctions occasoinally too.

Ive been told it is likely to be the air idle control valve but what do you reckon ??
I can get one for 30 quid and its easy to change but am afraid it might not be that and 30quid down the drain right now, i could do without !
Also, a neighbour said its the map sensor ?? would these be the symptoms if this was playing up ??

Thought i would check on here before i start replacing bits that i cant afford.....

Cheers in advance.......Andy

have a look at the hose i have seen a number that have cracked letting in air its a common fault ,when changing the air filter they bend the rubber pipe spliting it .
seen it loads of times.

i had same problem on 16v 1.2 corsa
on mine it was the crank sensor
hope that helps
cheers

AFAIK the MAP Sensor controls the idle speed, So could be that? Kicking in at the wrong times etc, therefore making it rev more frequently?

Im not 100% sure though..

Hi in 99% of cases it is ussually the idlde control valve. Most times if you remove it give it a clean and refit it's ussually ok.

A new one if required was i think about £27 but may varry depending on different models. Have had to do them on most family and friends vaxhauls over the years.

HTH cheers Matt

Ok chaps,

Ive checked the hose that thunderace mentioned but no signs of damage there, would have been the cheapest fix i think....
I have taken the idle control valve out before and cleaned it up, seemed to improve things for a week or so but its got worse again so think i will get a new idle valve for it and keep me fingers crossed.a friend had the same problem with a cavalier and changing the idle valve has transformed the car apparently.

If that doesnt improve it i will try to pick up a map sensor from a scrappy, thanks for the advice, will let you know if this sorts it out..

Cheers....Andy

my old corsa did that, was a 1.4 however with the same symptoms. changed the distributor cap and it was ok for a while, then after about a month, same problem again and needed a new distributor.
