Camshaft Deviation
Need some advice/ideas .
1999 C2
Durametric reads Bank 1 as 12 degrees flatlined idle thru 6000 rpm
Durametric has had reports of broken actuator spring causing this condition
But activating bank 1 drive link dramatically changes engine at idle -lumpy-have not reved engine in this state.This would seem to indicate actuator is good .
Would like to try same test on bank 2 but DME/Durametric doesn"t report it .
No codes-cel is not tripping
All comments would be appreciated

Have you set the Durametric to show the camshaft position on actual values and then run the engine up through the rpm range? You should see the advance kick in about 1,500 rpm and then kick out about 5,000 rpm.
Is this where you say it is flatlined and shows no change with rpms?
