AIC valve (stepper motor) ?????

[blingo driver]

Evening gents anybody know the part number for the AIC valve (stepper motor) on a 1.9d 54 plate and where is it ?
Rev counters staying bang on a thou revs where it used to sit at 15 thou till warm then drop back down to the thousand revs
So am taking it as the aic valve any ideas ?

Sounds more like the Cold Start device has gone. This is screwed into the thermostat housing on the van under the fuel filter. It operates a cable which gives fast idle on cold start and then drops off as engine warms.

Are you having trouble starting??

I thought stepper motors were only used on petrol engines.

My '55 plate 1.9D van doesn't have a stepper motor - I do know what they look like though :whistle:
