I'm having rev problems with my 2006 Holden Barina

Asked by Graham

My 2006 Holden Barina idles high on start-up, then drops revs and stalls frequently when coming to a stop. But it then starts straight away.

First thoughts are that the stepper-motor (which controls the idle speed) is faulty. That would explain both the high idle at low engine temps and the stalling and stumbling as you roll to a stop. This component is really just a small electric motor and shouldn't be too expensive to replace.

But have the car scanned first to make sure there are no other obvious causes for this behaviour. A faulty engine temperature sensor or some other small component could also produce these symptoms.
