OK, fixed the huuuge vacuum leak (thanks to Andy Duff on the phone blowing down hoses ), and now the AAC is controlling the idle (disconnecting it, the idle drops ~50rpm)..

 

But when opening the throttle any faster than very very slow, the revs drop almost to the point of dying, before shooting back up (dangerous in the wet )..

 

Anyone have any further ideas?

 

Oh yeah, forgot to say - the reason I want to fix this hesitation asap, is that the clutch cable snapped in the Renault last night - so now I have no choice but to use the Z... and it scares me when it decides to hesitate like that..

 

Thanks.. Az

does it also happen if you set the idle-rpm a bit higher ?

did you check the tension of the throttle-cable(s) ?

Eric,

 

I'll try raising the idle a little tomorrow at work (currently the screw is right in) and see if that makes any difference.

 

It's all freshly rebuilt, so the cable tension is fine (as far as I can tell) - it does the same thing if I blip the throttle directly via the quadrant under the hood though..

One thing to try is to check the balance on the both throttle butterflys.Pull off both tb hoses and using feeler gauges make sure when closed that both are set at the same amount of opening, a 0.5mm feeler should have a slight drag on it when trapped by the throttle.Also there are a couple of small holes below the butterflys make sure these are clear. Good luck keep us informed.
