Damon, what are the other problems you are having with the sunroof, window and radio? If you give descriptions, I am sure someone will help you. I have a '88 190 2.3 and just rebuilt the head. 3,000 rpm @ 60 mph. I will check this weekend to see 3,500 rpm. Does anyone really know where it should be given a flat road, no wind and a perfect car?
