Heres a way to test from the top of the egr system.
1st while the engine is idling using the hose going to the EGR dashpot, Suck on it, If the engine dies and you cant keep sucking air through it then the dashpot is good.
2nd the green vsv cellonoid over on the passenger fender is working ok, You can do a suck on test to see if its opening and closing right, I think the valve closes on a throttle decel.

If both of those are good then its the little black plastick disk thingy at teh front of the engine with all the hoses going into it. (It gets plugged with water and carbon sometimes)
Or the heat sensor has bad, Thats the one with the 2 wires coming out the side of the egr tube below the dashpot.

I think its the little black plastic thingy if the first 2 checks are good.
