    Im not sure what you mean by little brackets on the egr ?it looks like a round sealed unit with two bolts that hold it down to the intake unless you meant for me to take it off and then look inside but that looks like I will have to remove tha plenum to get it out

    There's a couple of brackets, kind of like the backside of a car speaker. See pic, right speaker. Press the diaphragm between the brackets, to pull the pintle downward.

    You don't have to remove it to test...

    The 90 uses a positive pressure EGR. Check this link for info on how to test.

    What's an easy way to tell which type I have? My car's a 96.

    Thanks,

    Jake, I don't know much about the LT engine setup, but I'm sure the EGR is easier to access than the L98. I would think that either P or N would be the last letter stamped on the housing, but that is just a guess. Sorry.
