im curentlly having the same problem as you guys but the cars starts good, my new potentiometer should be here today, i have a 190e 2.3 16v wich are a pain in the a!! to work on but i removed all of the intake system all the way to the intake mainfole butterfly and removed that too and theres a something like the potentiometer on the butterfly i think mine isnt working correctly, i have rough idle and got the car to idle a lot less rough but bow the car lost power, i removed the potentiometer and the black band was very worn, if i didnt put it back on correctly could that be causing the loss of power, i also adjusted the mixture, maybe thats the problem right, anyway im waiting on the new part. also does the 16v have an altitude sensor, and is there a vaccum advance unit on the distibuitor cap like the one i see on the haynes manual for the 8v? i tried adjusting the timing on my 16v by moving the distribiutor cap and nothing happened????


thanx
