Multispace 1.8 petrol strange idling problem

[GSLondon]

Hi all

Sorry for asking so much and contributing so little!  My Berlingo has developed an odd thing over the past day or so. Basically the idle speed is going up to about 1,400 rpm when in neutral, having just stopped, or is slow to go back down its normal 1,000 rpm idle speed.  Probably not explaining it too well - apologies - but I suppose it's like a sticky accelerator cable, except I'm not sure that it is.  Any ideas?

Many thanks

Hi, Yes make sure the cable if free and it's returning back. Also make sure there are no splits/loose hoses effecting the air flow.

Idle control valve

Thanks both. I'll have a look.

Hi all, back to the drawing board. The accelerator cable is moving freely and is not jamming. There are no leaks or holes in the air hoses. In addition, today the van nearly cut out (but didn't) as the revs went down to about 600 rpm. I'm not mechanically minded, but am going towards the ICV as the culprit. What do you reckon? What else could it be apart from the ICV? Thanks as always. Love this forum!

Like I said sounds like idle control valve,

Cheers Johny. I'll order one and see whether that cures it.

Hello GSLondon also check the mass air flow meter could need a clean or replacing be careful it can easy damage .

Let us know if you fixed it,cheers

Ta both. Have checked the MAF and seems okay. I'm picking up a new idle control valve - £90! - and will see how that gets on.
