Okay, then you were measuring ~28 in Hg (inches of mercury) of vacuum. I wouldn't have expected it to be so low, however, but I can't remember what I've measured when I've done this. Probably more like 15-20 in Hg. > >>your "pressure" sensor to the fuel rail? It SHOULD connect to a nipple on > the intake air regulator.

Right under the two intake manifolds, correct? I thought > this was the air intake distributor? Yes, this sounds like it's correct. > Anyhow, it's still giving me trouble :( Attach a clean hose to the nipple on the pressure sensor and suck on it. It should hold vacuum. Does it? Don't forget to reattach the hose to the engine when you're done. ;-) -- Jim Adney jadney@vwtype3.org Madison, WI 53711-3054 USA ------------------------------------------------------------------- List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org
