What about the original question about the oxygen sensor?
My '87 260E 110K has started behaving exactly as was described in the first post on this thread. The discussion took a detour into exhaust system rattles without a solution. My Benz shop is baffled. I need some brain power on this one.
Here are my symptoms:
Oxygen sensor light flashing on and off accompanied by the engine stalling and losing power but not completely dying. This happens at all RPM's, at all different loads, hot and cold but mainly hot.
Computer replaced 3 months ago. New oxygen sensor 3 months ago. New overvoltage relay 3 months ago. New cap, rotor, and wires 2 months ago. New tires, brakes and rotors all the way around - not that it should help.
New oxygen sensor within the last 3 days, computer swapped out during diagnosis - no change. Wiring harness inspected - looked good.
