hi can anyone tell me the correct rpm my engine would have idling. the car stalls in the morning unless i rev it alittle till its warm but then only
sits on around 600 rpms. i had the it at the auto mechs and they cleaned the throttle body and the revs upon starting went threw the roof so they adjusted the revs but i think it is too low, any help would be appreciated
cheers

Easy fix
1 Start the car in park
2 Remove ISC Plug
3 Adjust idle screw to desired rpm
4 turn off engine, reconnect isc
5 start engine, test drive and enjoy

There is a little knob on the ISC, start the car and adjust it until it idles smoothly, at about 800-850rpm?

ey?? the ISC has a knob? it has a black breather cap or something but this doesnt just the idle.. The idle is adjusted on the throttle body.. its a screw that limits how far the butterfly can close

Yeah, that sounds right (still picking up knowledge). The screw is gold isn't it?

First do a self test.
Your ISC maybe stuffed and it is not adjustable.
