my daughters wrx has a low idle. without the a/c on there is no problem but when using a/c the car will stall as the compressor kicks off. before i go on my own goose chase i would like to know if anyone else has experienced this and found the remedy.

thanks

Idle is supposed to jump up about 150-200 rpm when the AC is on. If idle doesn't increase the idle control valve could be dirty/sticky. Usually a cleaning and a new gasket will take care of that.

 

If it has electronic throttle you may need to clean the throttle body.

 

Also check over all of the PCV/Breather hoses and vacuum hoses that attach to the intake manifold, intercooler, and intake tubing. Make sure none are cracked/ loose.
