I have recently purchased a 406 2.2hdi executive. It is not running correctly . Seems to be pulling back when revs applied so much so that I'm scared to pull out when a hill climb is involved in traffic ! . I had it plugged in by a mechanic and no faults showed up . I looked it up on the Internet regarding egr valve etc and am wondering if this could be causing my fault. Any ideas would be gratefully taken ! . I am also looking for Doggyeric on here as I lost his contact details when I couldn't sign in on my old username so if your there contact me ! Cheers.
