I have an 05 GTO with a 2800 Vigilante converter. I have been having intermittent problems with 2nd and 3rd gear starts after a burnout at the track. It finally thru a PO722 code (output speed sensor circuit low input, old-immature) along with 2 PO300 codes. the DTC for the PO722 was already set to report no error but still did? I was also told to set code PO757 to report no error but its not shown on the list, any ideas? I'm not the tuner just trying to get some info to try and fix the problem.
