yea you can use a vacuum pump if you want. i just suck on the end of the hose and it will quickly start stubbling and stalling if its working.
if it doesnt stumble or die the ports are either clogged or the egr valve is bad. you might be able to get a finger under it and feel the diaphram moving but do this when the engine is cold egrs get real hot.
did you replace the sensor with the 2 vacuum lines and an electrical connector on it? thats the dpfe sensor which is ussually the cause for that code they just get stuck sometimes.
and what year is it on?
oh i assume its a 97 if you did intakes. this means you would most likly have the aluminum dpfe sensor replace it with the new redesigned plastic one.
