unstable idlling-stalling im going nuts

[leadfoot6]

no expert but i'm pretty sure it's just right.. the feeling is there, tightness and the response from the engine the instant i step on the pedal

That sounds OK.

But just to be sure.....is there any slack in the cable when you raise it up by hand before the throttle pulley moves?

I did not seem to find anything amiss when operating the throttle from the cabin, but I only noticed the problem when I opened the bonnet and made a close inspection of the actual throttle body.....where I saw the slackness of the cable.

will give you a good understanding of what is involved.

Note at the start that the throttle cable is very loose.
