My leak is on the "outside" of the tb. When I removed the tb from the intake setup, leaving both air valves attached, it idles at what is currently normal 1200rpm. If I put my hand of over the tb to plug it up, the idle drops and the car almost stalls then it rises back up to about 900rpm. That leads me to believe the IAC is doing it's job at that point.
Haven't blocked off either of the air valves. It is a 1.6 tb mounted to the top half of a 1.6 manifold welded to the bottom half of a kia sportage 2.0L manifold. The top have has all the OE 1.6 idle control stuff. At one point, way back, I had the idle set per the FM Link manual and somewhere along the way I had an idle hiccup. There was other stuff going on with the car at the time so I didn't pursue it - 1200rpm idle is definitely tolerable, but 900 is better IMO. FWIW the GA emissions actually allows a 1500rpm idle on my 90 Miata. :-\ On Jan 30, 2009, at 7:04 PM, Larry Alster wrote: > But if you have another leak somewhere else now, running the screw > all the > way isn't going to stall the car since you have air coming from > somewhere > else.
