I have a 2005 GTO with a 2800 Vigilante converter. I have been having a problem with 2nd and 3rd gear starts after doing a burnout at the track, not all the time, intermittently. I have been told to have codes PO757, PO751, and PO722 to report no error. PO722 is the only one on the DTC list and it still thru an error. The box was checked to report no error? Any help with this problem would be greatly appreciated.
