Grif,
I wasnt sure if you saw my original post so I will include it. I will try unhooking the power steering switch this weekend. Is this a fluid pressure swithch? Also I recently changed my IAC. It seemed to fix the problem but only lasted a week. I find it hard to believe that a IAC get durty in a week.

What do you know about the EVAP system? The one with the canister. It has 2 hoses runnig from it. One has an orangish band on it. They connect to a seleniod but which end goes where on the seleniod? The two ports are stacked on top of each other so I would refer to them as the outer an the inner. On the canister the orange banded one is smack dab in the middle on the top.

As far as the obd ii, thank you for your input. Ill do some more research and see what I can find. I think what I heard you say is that the information is there, just have to find a way to tap into it. I will post some charts that may help iluminate some of the problems I am having.

"I am having a hell of a time with my VX idling. I seem to happen when the engine is cold and start suddenly and occurs randomly. I get idle hunts when in neutral and in park. I seems to run great once warm. It is my daily driver. very short run to the freeway then 27 miles to work. Never a problem on the freeway. I put my ScanXL ObD II scanner on it and notice the following;
MIL Light Codes; P0171, P0172, P0174
absolute manifold PSI Max =14.9 Mean = 8.1 Min=2.8
short term fuel trim bank 1 Max=90% (sometimes at idle) Minimum=-21%
Long term fuel trim bank 1 Max=24% Mean=10% Min=1.6
Max Air Flow Max9.1lbs/Min Min3.8lbs/min
Fuel rate Max6.1gal/hr Mean2.5gal/hr

I have changed the IAC, cleaned the Throttle body, replaced the vacuum relief valve (mounted to the supercharger, opens when in idle to relief pressure back to uncompressed side of SC). I have re-installed the intake manifold to insure there wasn't a related vacuum leak. "

Thanks again.
