Right took the shitter for a spin, when cold the idle still rises and hunts but does try and return to normal, but once its warm while ur driving or stationary the revs sit at anything between 1500-2k, if u unplug the iscv and plug it back on its fine but blip throttle and shes off again!!

Seeing as tps readings seem on now ive adjusted it, and the fact its running rich, could a faulty CTS cause a problem like this?!
