The photo is of the threaded hole in which the probe threads into and the one that the wire broke on. Any help on what part number or what part it is to tell the GM parts dept so I can get it replaced? Is it ok to drive without this connected or will it throw a code? Thanks for the help in advance.
Are you running dsp5, or single tune? If dsp5, does it do it on all tunes?, stock trans? If stock trans, Nick may have left defuel for a reason. I would contact Nick to resolve it.
