I'm still stuck on your speedometer needle being eratic, that must be some kind of electrical problem. Did you double check your install to make sure everything was re-connected properly and that none of the wire are chafing. Speedometer needle is controlled by "PCM"(05-06) and "ECM"(07up) which in turn is just interpreting the vehicle speed sensor. HO2 sensors and VSS aren't even on the same supply or ground leads.
