'98 Z71, 5.7, 60k mi. Recently been getting this code and nothing else. Turned off twice w/obdii laptop program and returns.
Now this code will have you believe that your cat is inefficient. Long term fuel trim on both sides doesn't look bad. Both O2s are working but how fast they are working(lazy?) I don't know.
Anyone cured this stubborn code abd how?
