Can someone please tell me the full procedure for setting the base idle on an rs turbo, base idle screw seems to do absolutly nothing, its wrecking my head, also when my iscv is plugged it, it will idle normal then out of nowhere it flys up to 3000, then maybe down to 1500, then 2500 then normal and then 3000 again. Its very imbarassing in traffic and also changing gears because in between gears its revving up, i unplugged the iscv abd it drove perfect except for the idle being quite low, it has also started to run very rich on idle now puffing black smoke and really stinking. Any help lads??? Iscv is really clean and tried a different tps no joy, and tried both temp sensors with no joy!
