Sounds like the fuel pressure regulator

Ditto what Willy said...maybe replace your fuel pressure regulator and your fuel filter for good measure. Fuel filter is a canister shaped object on the inside of the frame rail on the passenger side near where the frame rises to clear the rear axle. A former member (Dino) wrote up a nice fuel pressure regulator replacement how-to: http://www.vehicross.info/forums/showthread.php?t=12021

Change the FUEL FILTER "first" before doing anything else!!! Fuel filters by nature are very fickle. Once your fuel filter is clogged, it's clogged for good and the only cure is to replace it. All of the symtoms you describe relate to a clogged fuel filter.
If the problem still persists after a new fuel filter is installed, then look at the fuel regulator as a possible culprit. However, I strongly believe your problems will go away by simply changing the Fuel Filter. In addition; use high octane Premium Gas, if you don't already. You'll be amazed how well the VX runs with a brand new Fuel Filter and high octane Premium Gas!!!

I have the exact problem on both VX's, just this last saturday swapped out idle control valve and replaced fuel pressure regulator and I dont think it has ever idled that smooth!
Thanks Jay, he took over and did my fuel pressure regulator!! AND gave me a Mr. Clean carwash.....I think that was a hint to wash it.....
