Code 115, coolant voltage and closed loop 02 operation HELP - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I am getting the 125 code which is " insufficent coolat voltage for closed loop o2 operation". I replaced my coolant temp sensor which I was getting a code for as well (115), Now that code is gone and the 125 still comes up. The car doesnt start right and doesnt idle right. Sometimes when I press the clutch in to come to a stop it will just die instead of dropping to idle. It runs great when I get on it and it is above 1500 rpm. Anyone have any ideas?
