I pulled the diagnostic codes from my 300E M104, 3.2l. It was coming up with an indication that the mass airflow sensor was having problems. Car would barely run at all after about a minute of running. Checked codes (see one of my previous posts on how to build the code tool) and found that the Air mass Sensor code kept coming up. I bought an air mass sensor (Ebay, $70) put it in and car runs very well now. Next step is to clear the codes and make certain that the O2 sensor is OK. It was showing up on the codes, also, but may have been a result of the bad MAS.
