2001 Cadillac DeVille 4.6L Poor Idle Quality, Surge, Stall, MIL Lamp on
This caddy has a rough, surging idle....constanly going from 500 to 650 rpm. It has codes 171 and 174 saying it is too lean. I have sprayed berryman all over it & found no vac. leaks, removed & plugged the egr, no change. .....EGO sensors all reading very low ...
