Hey guys...I did a search on here and found a post where someone told how to test the EGR valve...He said you attach a vaccum hose to it, with the engine off, and suck and the diaphram should move and then you hold the vaccum and make sure it stays in place...Well I sucked on mine (quit laughing), and nothing moves...I don't feel any resistance what so ever, just like sucking through a hose attached to nothing...The diaphram doesn't move, nothing...Also the vaccum hose that was attached to my EGR valve I can't feel any vaccum coming from it when the car is running...This hose runs over to some small black box thing on the passenger side back side fender well...Any help with this will be appreciated as I am trying to get my car running right, it has a s/c and I believe this EGR is just adding to surging/bucking/heat problems, or at least it certainly isn't helping things I would imagine...Please let me know what to do...Thanks,
Jason
