search for some of my older posts on rough idle, maybe 2 years ago? Things to do, things to check, sometime its just a combination of things to correct:
replace all vacuum hoses, they get old and develop small leaks which give rough idle, good preventative maintenance periodically anyway and very cheap.
check/replace the air filter
replace fuel filter if not done, they like to get filled up around 100K miles
Other problems can include valve cover gaskets that leak into the sparks and soak the spark plug wires, not good for idle, you get oil in the cylinders, and the wires lose ability to move current (conductivity?)
Here's how you find the IAC, just looking at it won't help, you need to remove and clean it, but just to locate it: stand on the driver's side of the engine bay by the wheel. Look at the intake manifold (the silvery looking thing on top with six tubes. Along the edge of that, closest to the passenger compartment its square/rectangle like a long thin shoebox (also its where the intake tube attaches on the opposite side). Put your hand (COLD engine!) on top of it, right at the end closest to you. Move your hand to the right/side, then put your hand under it, below where you started, you will feel the IAC, it's like the size/shape of a can of pop if I recall, maybe a little smaller.
To actually get to it, you need to remove the intake manifold for access, if I recall. Check for my detailed post on it (click on "more from michael p" above this post).
Good luck,
