Need so help . 1988 528e.
The switch on the thermostat housing all the way to the front is the thermo time stitch right? It should be closed above 120 deg F right? Car is running rich and failed smog big time at idle. All the usuals were replaced as O2 sensor. cap and rotor, plugs, valve adjustment and oil. But its rich. I now suspect the time switch is not closing and the car is dumping to much fuel.
