These two parts seem to have the same symptoms that would indicate something wrong, yet I can not find a desription an to where they are. Which one is attached to the driver side of the TB, i think that this is the IAC. If this is true where is the other and why is it so damn hard to get the friggin screws out. I have a feeling that this may be one of my longstanding problems and while im asking where is the pcv valve at been lookin under the hood for like 10 min. and cant find it!
