Moving you to the CTS forum friend. Because after 103 views in the customer service forum, you still had zero answers. Best of luck. :wave:

Thanks, Rolex!

Doug, I just replied to a similar post of yours in a different thread and I'm sorry I didn't see this particular thread until now! Email me anytime at Katie_Lucille@gmexpert.com with the last eight of your VIN and I can do some research on your behalf!

Had this happen to me several times, but it would straighten itself out after a few minutes of driving. I discovered that the apparent cause was that the V didn't like the ScanGauge being plugged into the OBD port. Removed the ScanGauge and haven't had it happen since.
