What kind of reader are you using to clear the codes? I have two, one that I bought from Advanced(little orange one), and one that my wife bought me from amazon(a cheapy). Oddly enough the cheapy that she bought will clear all codes no matter what they are and the orange one will not clear them. But more than likely you are getting the throttle code because at some point connectivity has been lost between your throttle and the pcm at some point.
