I pulled the vaccuum line off the valve and nothing happened. I revved the engine and held it a higher rpm and still nothing happened(no vaccuum). Does this mean that the egr valve is bad. I have been having a problem with rough idle, and keeping the car running at a stop sign. I have already changed the pcv valve and that seemed to help a little. Thanks
You have likely got a bit of carbon in the EGR that you can clean after you remove it, I usually spray some penetrating oil into the valve hold my finger over the hole that I sprayed into and turn the valve over, if it leaks the seat is dirty and cleaning the carbon out may help. also push up on the plunger several times to be sure that it doesn't stick alternate carb cleaner with penetrating oil until the valve is free and no longer leaks when inverted. As far as your question the test you described doesn't test the EGR or the EGR solenoid correctly at all. On some the car needs to be in gear to actuate the EGR, all you need to do is check that there is vacuum to the solenoid and that the EGR valve works freely. If the EGR fails to work the check engine light should be on and you can check the code to get a clue as to why.
