Un-even idle / engine hunting

[Peter255]

I have just run the Atom for the first time for a while today and its "hunting" quite badly at idle.

It starts fine and idles fine for a few seconds, but then starts to hunt from 1-2 thousand rpm cyclically.

It never stalls but hunts from 1-2,000 rpm. Its strange as it seems fine for a few seconds then starts this cyclic effect from 1-2k rpm.

Under power it seems fine its just the idle issue.

Ideas? It was running fine before being put away. No lights or anything on the ECU.

Cheers

My googlefu is telling me I need to find and check the idle control valve.

Am I on the right track? I have searched on here and I couldn't find anything in our forum.

Where is the valve and is it easily accessible?

I'd put money on it being the idle control valve. Sometimes they clog up if left.
I had the same thing with mine after I fit the supercharger. I gave the car a blast and it sorted itself out.

If that doesn't work you might need to take it off and give it a good clean. It's on the bottom of the throttle body

Hope u get it sorted
