I'm working on a '97 Lexus LX450. I just replaced the engine after it failed the head gasket. Now it's showing a diagnostic code of "P0125. Closed loop fuel system. Insufficient coolant temp." I have replaced the thermostat & cancelled the code but after about two or three miles, the check engine light comes back on. Thanks, Ray
have the same problem?
