'89 740 flooding, can't find cause 700

posted by  someone claiming to be George on  Sat Jul 2 01:56 CST 2005 [RELATED]

Hi Scott.
The engine has 2 temp sensors,one for the gauge mounted in the head under intake header #2 and another one for the fuel injection mounted in the head about under intake header #3 intake,and this last one is the ECT sensor.
If the ECT sensor is bad the ECU thinks the engine is cold and start dumping too much fuel to the engine.
Inspect also the electric wire connection to this ECT sensor.
Check the 700/900 FAQ under(electrical:Engine sensors) for more info about this subject.
Hope this helps,and keep us posted about your findings.
God bless.
George.
