DTC 121???? TPS anybody ever get this code??? I recently did H/C and while me and my friend were trying some tuning, I didn't want to mess up my throttle body so we used his old one that had already been drilled, put it on and worked great so I we kept it on. And now I'm getting this trouble code. Any ideas???
