As with most any modern car, vaccum leaks will drive you crazy until you track them down. Often O2 sensors are replaced when it was a vaccum problem. Also...the Intake Manifold Runner Control (IMRC) can cause problems....but there are specific codes for this.
Idle speed is controled by the Idle Air Control (IAC) which is on top of the upper intake manifold...right next to the throttle body. It is held in place by 2 bolts....and has an electrical connector. Very easy to replace...not real expensive..Can "stick".....Many have corrected IAC sticking by some WD40.

I'm trying to get in contact with the mechanic to get the codes read.Unfortunately here in Canada( at least my area) there are no places to get the codes read for free.I was told that the O2 sensors appear to be the fault, but somehow I don't think so. And as far as I was told, no leaks.For some reason I think its the EGR Ports, but I'm not a mechanic so its just a guess.
Is this IAC part of the vacuum system? How can I check it?
Thanks
