i mot'd my apprentices 1.1 single point injection L plate fiesta last week it only failed on high co% around 0.5/0.6 at idle upto 0.80 fast idle limit 0.30.lambda sensor is ok,a few errors from the code reader-
coolant temp sensor-
air temp sensor-
air flow sensor-
oxygen sensor-
speed sensor.
does anyone know how i can test some of the above items?or where i can get a pdf workshop manual.
the air flow or air temp was disconnected white 2 pin plug on rear of throttle body,re-connected emissions still the same.
is the coolant temp sensor for the ecu the one in the thermostat housing 2 pin blue connector?makes no difference dis-connected.james
