i just bought an 88 190e with the 2.3 and im setting at round 3000-3500 rpms and round 65 to 70

 

hey guys i have a 190E 2.6 also and mine does the same thing. i just let it go cuz i didnt want spend money on something like that. but i am kinda glad to see i am not the only one who thiught that this was a problem.

 

Me too. My 1990 190E 2.6 seems to prefer 3000. Watch your fuel economy indicater, it seems to be most efficient at 3000 rpm's at highway speeds.

 

That seems correct. I have a 88 190E and it runs at the same speeds. (Speed vs RPM)
