16 is Distributor Ignition System (low resolution pulse). From my understanding it's a stored code and not too unusual. Clear it and see if it keeps coming back, if it does check the OPTI harness connections first - doesn't necessarily mean the OPTI is bad. Not an LT1 guy so I'm not positive, someone else will chime in.
