I swapped out a DPR from a fox too see if it worked.And it now dies when revved up and goes back too idle, with either my Jetta DPR or the Fox DPR . I replaced the O rings. Not sure why it wont at least work with my original DPR.

Your post seems to be leaving some details out or something. Why did you swap the DPR in the first place? You say, ". . . to see if it worked.", to see if what worked? Are you saying that before it was fine and now it dies at idle with either DPR installed? I think, for me at least, you need to spell things out a little to understand just what your problem is here.
