Idle question

[Matt#]

Hi guys,

This has only started over the last few days. Cars is running fine but as soon as I dip the clutch or standing on idle in seems to rev on it's own up an down from 1000 rpm to 1500 rpm. Then it settles just over 1000 rpm an is idling to fast. Any thoughts would be a help

Thanks

Anyone got any ideas?? I'm thinking could be idle control or auto choke ??
