call rrm. There have been other reports of this. I think it ended up being an install error, but I'm not 100%.

i sent countless emails and no one answered me back and tried calling no answer. guess ill have to try again this weekend. figures also the SES light went back out on its own and i also noticed RRM pulled the PZEV header and the CEL box off there web site.
