ZCC,

CEL stands for "Check Engine Light".

MB DOC,

It has a new O2 Sensor, I just replaced it yesterday. Why does the X11 Connector only show .08V DC? And why is there not at least 4.5V DC at the Air Flow Position Sensor? I ask this because I went thru some of these tests on my 300SE.

This monrning I had a heck of a time starting it up, it took several minutes of cranking before it finally started and ran but only with the accellerator depressed. It seems like it is running lean but the fuel bowl is wet.
