Hi there,
my friend has a 1998 R, vauxhall corsa 1.0 12v. When she is driving along, the engine revs fine, and all is well. Until she comes to a stop, as the engine returns to idle, the revs drop to 400rpm, and the accelerator has to be used to prevent it from stalling. Once the accelerator has been pressed, and the engine revved to about 1500rpm, the revs will return to normal idle speed.
Does anybody know what this may be?? and if it will be expensive??
Cheers
Dan

any ideas?? cheers

This is a common fault on Vauxhalls of the era, and is quite often expensive -- new valves etc.
However, I've not heard of it on the 1.0 which is a Suzuki engine, so not really sure what to suggest.

Dan,
When was the vehicle last serviced? does it do short runs per day on a reasonable run. How many miles on the clock?

Hi, sorry for not replyin, i have been away.
Corsa was serviced about 3 months ago.
the problem has become gradually worse, and now, the car cuts out completely when returning to idle, but will start again perfectly. I have been told problems about EGR valves. Please, any assistance is greatly appreciated.
cheers

I would suggest this is a fault with the idle control stepper motor.It is very easy to replace ,secured to the throttle housing by 3 torx screws.Part cost about £70.A diagnostic check may show this as faulty.hth

Last time i had one of these wonderful 3 potters i changed the whole single point injector lump from a low mileage breaker.
As eacdea says its the stepper motor usually ,you can tell by putting the ignition on and the thing goes in out in out and probably shakes all about.
Fix it and shoot it away OP as you will be replacing the maff next and these are still £150 for this model if you buy one with a name on like bosch rather than kaboschk
