Does your DMM have a duty cycle ability?
If so measure the duty cycle at pin #3 on the test connector. 50% on/off ratio

It does and I am getting 45-50% fluctuating...That's the reason why my overfueling is confusing the heck out of me. I have soot in the exhaust, o2 sensor coloration confirms and my fuel economy is ~12mpg. Filled up today. Got 178mi this tank before the light came on. Terrible....I was getting ~300mi to a tank before.
Since it is overfueling, I attempted to lean out the mixture, but the car idles worse and stumbles, a little more lean and it just flat out dies.
I ordered an EHA test harness from MB so its on the way to me from Chicago...Should get it early next week.
