gti running problem

Hi all i got my justy up and running and i must say it starts and goes well,however when its upto temp and i give it some welly it often conks out at idle but restarts no problem.

Any ideas would be appretiated please

I take it youv done a gti conv?
Prob just needs the revs bumping up a bit, if your using an o/e t body, theres an idle screw near the back of it, make sure its fully up to temp and you have the lights and heater blower on
If it still does it maybe the blue idle valve bolted to the front inlet mani has died

Thanks dominator i will look at that cheers
