Hi ime after some help on how to adjust the idle on my zetec turbo engine. The engine is running pectel t2 managment and a cosworth throttle body, the engine is idling at 2400 and want to set it to 900, I have tryed to adjust the idle screw on the body but it hasnt droped even though its all the way in and i have disconected the throttle cable aswell just incase that is holding it open slightly,is there any thing else I can do to lower the idle? Or will I have to have it remaped as the whole engine spec has changed since it was last maped
