    you more than likely have a vocume leak or a frayed air hose: at higher rpm, the engine develops enough suction to intake manifold to run smooth enough but at idle its not sustainable so irratic condition and stalls.

    most common vac leak is in or around air/intake hose area. a good visual solves most problems, you may even hear the hiss!!!!

    dont seem to be any leaks around the air inlet but what i have noticed is it idles okay but if i switch on any electrics or turn the power steering it idles erratic for a coulple of seconds and goes back to normal what do you think
