hi i've just recently converted my xr2i to an rs turbo which has been the biggest pain in the a** ever right well i got it sorted in the end but i'm having a few issues with it, which are;
when i connect the idle speed control valve the revs shoot up to about 2000revs and then eventually drop back down to normal after a moment but once you touch the accelerator it does it again, so i've disconnected it to allow me to use it normally,

the other problem is i'm not sure if it has any relation to the idle speed control valve not being connected but if i drive it hard say racing someone when the revs get upto about 3500revs the car splutters and begins to jerk but once you lay off the accelerator and press it gradually its ok,

please help its getting to the point were i'm thinking of scrapping the whole lot
