I know this has been touched on but i cannot get my truck to not idle at around 850-900 rpm, i have tried reflashing the truck, made sure that it selected egr has been modified ect and no matter what it high idles, i tried street, xstreet, xrace and different trans files with all the same results, i checked all my exhaust sensors and they are hooked up, i dont have any codes at all... im at a loss...
