hi I own a 2003 cts I have replaced my throttle body twice already as to no avail. whats happening is it revs uncontrollably with out my foot on the gas sometimes at an intersection I have to shut the car off cause its revving to 5 grand!! each time ive had the throttle body fixed my car ran great for a day or two then back to the same issues. one more thing it does is when im driving I get a reduced power message on my screen as well causing me to have to restart my car. does anyone know what could be cause my throttle body to keep failing? im all out of answers here
