X2 on the IAC. Clean that and reset your fast idle throttle valve or fitv
Iac
for the Iac, it's located on the back of the intake manifold, it's held on by two 12mm bolts, unbolt them
pull th unit back then pull of the sensor that's facing the drivers side, after that remove the coolant hoses that run to it, once you do that, get some intake or carb cleaner and spray it into the mesh screen port, get enough to fill it up, shake it around then dumb it out. Installation is reverse of removal,
Fitv
the fitv is located right under neath the throttle body, it has 3 bolts i believe, after you take the 3 bolts off, take off the hose to the right side of the unit. after that look at the left side and you should see what looks like a brass colored plate. remove the plate and you will see a white nob looking thing, spray some cleaner in that as it's more than likely going to be dirty, next very carefully get a flat head screw drive and turn the unit clockwise until it's all the way down. you will feel it, when it gets to where it needs to be. don't over tighten or unscrew all the way up then back down as this may cause the spring inside the unit to bend and leave you with a bad working fitv.( I did it to mine and it would still idle like it was bad even though the nob was all the way down.)
after that slap it on and your idle should be good as normal. I'll look for the G2ic write up as it has Pics so you can actually see what i'm talking about. hope this helps
