Okay, on an 88' Federal car...Bosh K-Jetronic...
Anyone have any damn idea at all as to how plugging in a WUR can cause the Frequency valve to fail to operate correctly???
Below is a list of what is new. Not particularly because of this issue... but new. Some of the parts I had on the shelf and did put in to see if there was going to be a difference in operation... the WUR is new from the Special T Auto.
WUR
Frequency Valve
Lambda (O2) Sensor
Fuel Filter (no abnormal sounds in the pumps)
Alternator
RPM Relay (blue base)
Engine Control Module
RPM Relay (black base)
The frequency valve is very intermittent... and sometimes not operational at all... then unplugging the WUR it kicks right in and the car revs appropriately. It does not seem to be all that rich without the WUR plugged in either...
The wire diagram shows a very simple connection point with power coming to the WUR from the frequency valve to ground with a split to the AUX Air Valve to ground.
There is nothing else running to this damn thing! 2 wires in a series...
