And I don't know if the OP is running a 2.1 or 1.9 but on the 1.2 the big hose from purge valve goes downstream of the AFM into the "T" at intake manifold. This is the hose I was referring to. Like this: https://lh5.googleusercontent.com/-AQrHsssnpvM/T-0C3cqisxI/AAAAAAAAF38/f3FPZAq98as/s720/EVAP%2520Purge%2520Vacuum%2520Leak.jpg It seems that Digijet also has that same hose going to the intake manifold. Sorry for not being clearer about what I meant! Neil. On Sun, Aug 26, 2012 at 5:34 PM, David Beierl <dbeierl@attglobal.net> wrote: At 06:51 PM 8/26/2012, neil n wrote: > >> thanks David.
