"Apply 10 in. of vac w/hand pump to EGR vac port with engine @idle. Engine should attemp to stall or run very rough.

If NO, EGR is not opening or the tube is plugged." A Dalton

---Performed test, no difference in the way the engine ran the dreaded clogged EGR tube! I will let you know whether it takes two hours or two days to get it resolved!

Thanks again A Dalton!
