Hey Mark

That is what I was thinking. I do actually have 2 KnownGood ECUs & as I stated in the EM I posted back on Sat' (when it appeared as though the IdleStab Relay might have fixed it) I swapped in an ECU right after D15 looked OK & the RISS occurred again about 48min's later. I put my Spare IgnitionSwitch in it this morn' & drove it to run some errands & it was doing fine until about 3/4mi's from home @ about 30mph when it ShutDown & INSTANTLY Restarted on its own ~ the Tach did dive toward zero but it was back running so fast that it did not get all the way there. It will be just my luck that this thing has 2 issues that are displaying similar symptoms ~ hate it when that happens!
