I put this posting on 05-18-2003 and so far I have got 3 responses and 2 of then were from me.....I thought a nice ACC problem, on a 86 300e...124.030..would bring out a few people, some that know what they were talking about and some that didn't have a clue....True an ACC problem has alot of ups and downs (tempature Pun)...and might not be as exciting as a discussing of what weight oil to use in a 123...but????.....I did notice as I did my search for related threads that they were many postings that had tought, but important questions and NO ONE RESPONSED...Oh well maybe next time......
