as I have posted before, I have had some hesitation on my 87 300E whenever I accelerate from a stop. I found this page on the MBCA website the other day and tried it out; http://www.mbca.org/MBCA_Rough_starting.htm
I simply spliced and soldered in a 470 ohm resistor in series with the engine temp sensor. now the car starts right up and takes right off!
