The Paperclip trick didn't clear the codes on the car I used it on. I used to have an 88 IROC-Z Camaro. When you stick the ends of the paperclip in the top rightmost ports side by side, the check engine light would flash the identity of the trouble code. For instance, the MAF sensor trouble code is 34 The light would flash three times, pause, then flash 4 times to give the reader the identity of the engine issue. I never was able to clear my codes with this method though. Thanks for the info guys, I had a feeling that the OBD II system would be impenetrable without advanced tools.
