HighRolla Forums Junkie Location: Sydney Registered: January 2004	Re: 4AGE hose identification Tue, 24 February 2004 12:42 I don't know if I'm quite with you on that - I know what I've shown as the A/c idle up (marked in red) works when the car is warm. Pic 1 of my pics shows the a/c idle up control valve in the top right (right of windscreen wiper motor). This takes air from the air box - follow the pipe from the valve (you will see). The air is then drawn in through the lowest one on TB (marked) taking air from the outlet of the valve. I know this for a fact as where it connects to the air filter box I disconnected it - with the a/c on you could feel the suction, and turning the A/c idle up valve changed the amount of air sucked and hence idle speed. This was all done on a warm motor. I don't know whether this would be different on later GE's as mine is one of the earlier ones. I'll have to read scorps' reply again. The water heater connections at bottom of TB operate the Auxillary AIr Valve..i don't know whether this is referred to as an idle speed motor - maybe the GE doesn't have one?? I've read about idle speed motors before though..thought all EFI cars have one Quote: Now as well as the above electronic controls there is also a purely mechanical device which operates as the engine warms up - the Auxiliary Air Valve. Thankfully its much simpler than it sounds -its just a waxstat valve that controls a small air bleed around the throttle plate. When cold it is open, so giving a lift in idle rpm. As it warms up (its fed by coolant), the wax capsule expands and progressively closes the valve to stop the air bleed and hence the rpm lift. It is physically located under the throttle body and is a simple bolt on unit. Have a read hear - these guys seem to know what they're talking about http://www.mr2mk1club.com/repairsp15.html We're making a meal of this one aren't we [Report message to a moderator]
