GQ 2.8 Aircon Idle up
Posted: Thu Aug 27, 2009 9:40 am
Hey i notice on the injector pump of a 2.8 turbo that there is no vacuum solenoid to push the idle up once the aircon compressor is engaged. Is this normal? It drops about 200rpm and I would like to know what the factory setup uses to raise this idle. Pics are more than welcome. Cheers.
