most random evo problem EVER! wtf??
OMFG!! INFID3L, I bought my RS new in 2004 and I've had this problem from day one. I brought it in to the dealership at least twice and the best they could come up with was to put a check valve inline. Mine is also on the drivers side sprayer but now I've got some damage to the paint around the sprayer and they are probably going to repaint it because of this. I've just learned to deal with it. Let me know if you figure out what it is.
