IAC valve? Fabrik8 will post shortly, if you have already replaced the IACV then I'm not sure on what to tell you. Or try checking the fast idle.

if it's not the iacv which is easy to check jus tap it with a wrench but you say it's burning oil could be your manifold gasket or a cracked valve try the manifold tho

Re: problem with 93 eg
the smoke color is white, sweet smelling. i just took apart the head and found out the head gasket is bad and i have three bad vavle seals and i just cleaned the iacv and that took care of the idle problems thanks for all the help
