So I replaced the IAC on the 01 and the new one came with a typical gasket but the iac did not have a gasket like this new one. The old one was a blue 2 connected type O ring seal that sat in the circle grooves without a normal iac gasket like the new one came with. So I left the blue O ring seal in and put the new gasket in place with the blue O ring in place as well. The idle is worse now than before. I am wondering if I should take the blue O ring gasket out and use only the new iac gasket.
