Good to know. I just went to the Junk Yard again and I found a nearly new EGR and I picked up a IAS or IAT which ever it is, I have taken that apart and cleaned it real good, I'll switch it out along with the EGR one at a time and see what happens. If that is no help I will do your test with the multimeter and then I'll look at a thermostat.
Thanks very much for all your help.
