TurboJesus 09-23-2002, 04:53 AM I have a problem with my fuel man.... For some reason its dumping way too much fuel into the motor. Its to a point were I have to change the oil three times in two days. I have everything set right but still doing the same thing. Anyone have any ideas? TurboJesus 09-23-2002, 06:15 PM anyone?? unlucky 09-23-2002, 06:29 PM leaky O-rings?

I just threw that ECU code. kenley_ser 09-23-2002, 09:48 PM check your fuel injectors, one of mine was leaking and flooded my cylinder and leaked through the o-ring, are you overheating??cause I was so maybe the ECU sends more fuel to try to cool it down cause it does whatever it can to run cooler. It may be your coolant temp sensor. hope this helped charlie2020 09-23-2002, 10:27 PM Originally posted by TurboJesus Will the coolent temp sensor cause it to run rich? I just threw that ECU code. Yes, it will as any EFI sensor will if it is malfunctioning. The ECT sensor is a temperature-sensitive resistor that monitors the coolant temperature. The sensor is threaded into a coolant passage. As the coolant heats from the engine use, the resistance of thermistor inside the ECT sensor decreases. The resistance change, causes the sensor reference line voltage to drop in proportion with the resistance change. The ECM detects the temperature change and adjusts the air/fuel mixture to compensate for the change. 91-94 Sentra SE-R ECT Specs http://www.cybrrpartspro.com/Chilton%20Images/8816/88164g43.gif unlucky 09-23-2002, 10:48 PM when you put new o-rings in.. did you pressure up the rail with it out.. to see if they sealed? If you don't install them carefully.. they will get pinched and leak even when they are new. Travis | ||
