i got a question about the body throttle. my engine idle is around 650-800rpm (is it normal idle?) and i remember there's a little screw against the body throttle trigger. i did tweak the screw abit till idle reach 1000rpm. then i drove the car around later discovering a high water temp rise. then i later tweak back to 650rpm.. does the body throttle affect the ecu to turn "limp home mode"?
