Undulating/unstable throttle at idle - Peugeot Partner 2005 1.9 @ 160000 km

For some reason the idle speed switches between being stable and undulating. If I increase the throttle, it will stay stable at a higher rp, and it won't undulate while driving.

Maybe the waxstat?

Thanks for the quick reply. Mine is a 2005-model, and I have the DW8-engine. Does it still have a waxstat-controlled idle?

going by the age of your vehicle, 2005 , the engine will be a DW8 B version which will have electronic idle control
