Hi, have had two 850/94s in my fleet. at 250k km the sportswagon reacted critically slowly in exhaust testing...

I took the sensor off, dipped it over night into carbon cleaner liquid (for one family warming oil pan) and burned it clean with garden grill flame. There after the response in test was perfect.
The sedan (still in family) got the same treatment few yars later and I think I recognized light improvement in mi/gallon, still running the original o2 but only one in the design as N/A engine.
Never rub/scratch the sensor surface.
