Hi All...
I tracked down a freind who had the "Toyota Type 2" Diagnostic plug. Error code “71” ERG sensor.
I have to open it up and see if its plug up with carbon or maybe the valve has gone bad, either way I think it will be cheaper than replacing O2 sensors.
My baby is getting old now… she just about ready to turn 180K.
Best ten year old car I have ever owned. :D
