Hunting Idle

[1200det]

Vehicle is a UZS131 Crown and the idle is just hunting from like 1000 - 1500 in perfect timing up and down.

I have cleaned the ISC with carb cleaner and seems when i remove the pipe that connect the ISC to the intake pipe after the AFM the car idles fine ?

Any ideas ?

Replace the 2 bearings in the ISC.
They are small and easy to do..

Ive just done as per the manual in regards to checking the ISC operation via hooking power to the isc and nothing is happening ?

Blown-SC - Could that be the bearings ?

I have the ISC open and can see the bottom bearing and a magnet ? How do these work ?

Come apart from hear on in ?
