right now it idlin erratically wen i got the ac on n d car n drive ....so i hope dats d problem....

also y i ask is dat i know d valve is wat really openin n closin to let air in....so if dat hav gunk can i spray it tru d port instead of takin off

could also be a vacuum leak , etc causing the hunting

i had the same problem a while back i have a d15z4 i wen through all d sheit clean icav take it apart soak the TB all that still was erratic wit the a/c on funny thing i said to hell wit that so weeks passed to my a/c to get gas up n they told me my a/c fan wasn't working at speed like the normal speed that an a/c fan worked at but to me it was lookiing like it workin buh i said wat d hell n i went home n change d fan an suprisingly that was it for me the idle went back to normal after that so check wit an ac man first n see.. if not check idle speed motor or compessor switch and also spray some carb spray on vacuum lines to see if its a leak other than that check an ac man see if ur fan is up to speed that was my experience with bad a/c idling with a/c on

got the same problem on the crv and it was the ac fan, wasnt working causing the compressor to overheat

ok fellas i cleaned out the iacv....it solved d problem where it over reving in gear....car idles at 750rpms n wit ac on it goes up to about 850-900rpms...i tink dis is spec...il lower d idle screw a little ...funny ting is dat wen i now cleaned it out n did d ecu reset procedure...d car still gave me sum probs......i ran it on d hiway at normal speeds....normal i say......jeje....n d nx day d car purrin great..no more over reving...i guess it has to re-learn d idle with sum normal driving conditions...tanx for the info fellas...
