When I obtained my 82SC, the entire Lamda circuit was inoperable due to the O2 sensor not being plugged into the wiring and the wiring from the Lamda box under the passengers seat to the Frequency valve had been shorted out sometime before as it was extra crispy. The car ran and drove fine---probably because the mixture was set very rich---but it wasn't how the system was intended to function.

I plugged the O2 sensor to it's connector, reaired the wiring from the Lamda box under the passengers seat to the Frequency Valve and set the mixture to the spec CO reading---which apparently meant a LOT leaner than it had been running. Everything was fine and dandy.

Then one day the actual Lamda box under the passengers seat decided to retire. Kaput! The car had absolutely NO power and actually idled so bad the rear end of the car became a paint shaker. Sourced another Lamda box and all was well again.

Long story short, if it aint broke don't fix it!
