Answer
Hi Rick,

      You need to tell me what engine you have because there isn't a code to83 for the 4.9liter engine. However there is a PO83 for the 4.6liter Northstar engine. It means that the 24X reference signal is high. Basically it means there is a problem with one of the crankshaft position sensors/CPS or the wireing to the ignition control module from the CPS. That engine has 2 CPS near the oil filter. They should measure between 800 and 1600 ohms. If out of that range it needs to be replced or stalling can happen. In '00 Cadillac had a campaign on the '00 Deville with the 4.6liter and if one sensor was bad it was recommended that both be replaced. So if one of your CPS was out of that rage replace both of them and I would reccommend useing an AC Delco part because some sensors out there aren't very reliable.

     Give that a try and let me know if you need anymore help. Bill
