Im out doing a tune up on my 2000 grand am and I decide to clean my iac and egr to fix my rough idle. I go to find the egr, and lo and behold theres nothing but holes and remnants of an ancient gasket. I was given the car not too long ago, so I have no Idea how long its been missing. What's the deal with that? Could there be any reason someone would just remove it?
