DTC plug in front of the battery

It was reading, at op temp, at idle, floating between 19-25%. If memory serves fault codes are read out as solid percentages. I.E stuck at 50% would mean O2 sensor fault.

19-25% is pretty rich if I recall correctly.

I do also have this issue where the car, when cold, never wants to start up on the first time. It'll stall out immediately, second time it will start but run harsh until rpm's pick up. Then its fine.

Awesome news on the cruise! I'm glad to hear it! My 190's was one of first or second units I did, its still running! My 300D's has the most miles (of any that I know of) at 71K, still going strong!
On my 1990 300E, it's mounted on the firewall in front of the battery (see pic). Even though you transplanted the M103, given the year of your 201, I thought that it might still have it.
