For as long as the car has been running I have been dealing with intermittent freak outs from the idle controller. Its a ford falcon AU type with a couple half inch nipples tapped into the ports. I have finally gotten to the bottom of it. After playing with the electronic side of the system extensively and deciding I could have it perfect one day then it would hunt the next, I was at my wits end. I decided to pull the controller out and investigate. Glad I did. I think one of the nipples I had tapped and screwed in was ever so slightly rubbing the plunger inside the controller, which was making it stick open, or hang in certain positions. I always noticed it would be perfect on a warm sunny day but be terrible on a wet cold day. Turns out the temperature must have been enough to adjust the tolerance of the problem, as there was only the slightest mark on the plunger to indicate that there was rubbing once the fittings were unscrewed. I cleaned inside the controller, it was clean anyhow, but just to be safe, then gave it a small shot of inox to keep it moving smoothly, and then ground 1.5mm of brass off the threads on the nipples and screwed it back together. Viola! Perfect, stable, idle with a controller that seems to do its job properly. Turns out all my setup is great as it works perfect now its not restricted! It was always worse when cold and once the idle controller itself absorbed some heat it would work ok. So of course I celebrated by driving along Clear Mountain road for a test drive, I love that place, close to Brisbane and can see all the way to the glasshouse mountains. Its my ultimate address.
