I bought some hose and extended it from the #16 hose into the passenger seat ... hooked up the vacuum gauge and went for a spin. Brought it up to operating temperature and tried holding it steady at about 40mph (1800 rpm.)

There was not a stitch of vacuum. Never registered at all.

I brought it back and let it idle for a few mins and took another spin. This time, as I put it in drive and headed down the long driveway, it registered about 8 inches as I was creeping along around 10mph. Stopped at the end of the driveway and accelerated out onto the road. Vacuum held steady at about 8" ... for about 15-20 seconds then dropped to zero.

I held the speed steady at 40mph but no vacuum registered again. Brought the car back to the driveway and parked it. Revved the engine a couple of times ... no vacuum.

Sooo, there it is ... any thoughts?

I'm going to guess it's either the solonoid or the main computer.
