Duty cycle 81%? What does this mean for a 91 300e?
Got a multi-meter with a duty cycle. Followed instructions, red in #3 black in #2 in the test socket on the 91 300e.
Turned on the ignition, but before starting 84% reading and even after the engine is running I still get 81%. The value does not fluctuate.
-Does this mean the oxygen sensor is bad? or .....
-Does this mean the air/fuel mixture adjustment is off the charts?
