Well, Dr. Semple saved my hide again. The distributor was out of its window. One tiny twist and up it came! The OXS light stays on all the time. Connections on the sensor looked fine, im guessing its time for a new one? Would have been a piece of cake when I had the engine bay empty.. Figures. At least its the single wire one, so they are cheap. Thanks all that responded, Im now on my way! Bob
