I'm trying to put my Idle Air Controller back on but I need to know where the air hose goes into. I know its the fat hose on the IAC but I don't know where it is plugged in.
Just make sure it's connected anywhere between the throttle and the air flow meter - have a think about it and all will become clear. Any air that goes in there has to go through the AFM, and do so before the throttle...
If there's no AFM, there's no real reason why you can't just stuff a small filter on the end of the valve - presuming you're not using a turbo or anything of course! The little filters they sell at gasresearch for the end of blow of valves would probably do the trick, should be reasonably cheap from any larger LPG conversion place.
