How great it is when a Merc finally runs like a Merc, Congrats!!! I too just figured out the problem with my Merc it was the idle Control valve, 2 days ago I must have sat in the car for 20 mins and just listened to it humm, after just installing the New (used) ICV. This Forum is really just great!! if it wasn't for it, I probarbly would still be riding in one of the best looking and worst running 126's, but now I guess I can say the same for both!!!

God Bless!!!!
