Well it has bean almost a year from my last post on the subject of the intake system on this 420sel and I am sorry to report that not all of my work was successful, the wet intake chamber is wet as it was in the start of the work, though I have acquired another car (190E 2.6) it has two troubles, one wet intake and poor restart after warmed. I may have a little trouble with the fuel pressure valve, will have to check all of that system though it gets 25mpg hw, and 20.6 in town, I'm happy just need to do the fine tune. JNT.
