The issue you having is a common one, however it can be caused by a general set up problem or as you mention a faulty idle control valve.

The fact it ran better with small leaks suggest the base idle is set too low, this is the mechanically set minimum tick over speed, there is an adjustment screw for this on the side of the unit when viewed from the battery location towards the rear of the engine ( plenum) there is also a yellow plug on the unit that can sometime come adrift or become a bad connection that can cause idle recovery issues such as when revving up and closing the throttle suddenly that will cause a stall.

 

Of course there is also the possibility the idle valve solenoid has failed, no biggy to change but needs checking out first before writing it off.

 

Throttle balance, tps and timing are all areas than can contribute to the problem, so much easy to sort it with diagnostic equipement.

I've got to check out the missus Z tommorrow, similar problem, its an auto n/a we just got for her.

 

Has stalled at traffic lights twice just as she comes to a stop, but she reckons it's idling "just under a grand" factory manuals say 750-900, so i'm guessing a failing idle air. What would you reccomend i idle this thing at?

 

She says if she keeps a grand of revs on as she pulls it to a stop it wont stall, but i don't really want to have it idling at 1k.

Mine idles at 900 rpm always has.

thanks all i may have a drive down to zed world hopefully i can get a few pointers on how to set the beast up the throttle ballance thats interesting because you can move the butterflys one by one but wen i move the one on my left (as im facing the car) not a lot happens but the one on the right responds ??? i dont understand ive took the boost pipes off and felt both turbos and there deffo pushing some air ! ill have a look at the little adjustmant screw thanks jeff

i think i may take a trip down to see you jeff are you guys open tomorow ? thanx

my car starts but then cuts out anyone help me

also car has been standing for 6mths put new fuel in it £20 worth but still cuts out
