idle fluctuates when a/c is on

[Hanren]

sir, ung sakin 96 corolla gli na matic...if a/c is on nag idle sya sa 1000rpm, at pag bumuga ung compressor ba un ng a/c??? tumataas sya ng hangang 1250rpm..........has this something to do with iacv also???

thanks!

opposite naman siya dun kay chorb.. Im not sure about your case pero ang IMO, the iacv (or servo or idle up - whatever they call it depende sa car brand) is used to maintain the idle settings to the same level whenever the a/c is on. In your case, baka sa ECU settings na yon..maybe you can have your trusted mechanic do the diagnostic tests or let's wait for other inputs from the gurus here ...
