My cars RPM drops when I switch on the AC. So I need to keep pressing the acceleration pad when at rest. Its fine when I'm driving the car its alright but when I get stuck in some traffic I got to turn off the AC.
Its so hot in summer, if some one provide an useful solution it would be highly appreciated.
Its a Lancer evo VIII
You could have either a clogged or stuck IAC valve. Try opening the idle air screw a bit ( say one or one and a half turns ) and see if that helps.
If not, it could also be something like the bearings on the compressor seizing up.
clean throttle body most likely it is full of carbon, and removed the idle control valve clean with fuel system cleaner buy it at any parts store :)
