I have the setup in my sig. once I drive it for a few minutes and come to a stop or push the clutch in it dies. It won't stay running if I push the clutch in. If I keep the gas pressed it will stay running. Sometimes (rarely) it will idle when I come to a stoplight. When it does that it idles at about 1000-1200rpm. It kinda hesitates in 2nd gear too. before I rebuilt the motor, it had a surging idle at times but never died on me. So I'm thinking since I had a suging idle problem before the rebuild...could it be the IAC? The dieing at idle happened with (after rebuilt motor) speed density and mass conversion. I have the fuel pressure at 36, I tried 32, 34, and now 36 and it dies still. The mass air meter I have installed is a Pro Flow, which I was told is same as Pro-M. Its a 75mm calibrated for #24 injects which I have. any other ideas besides IAC?
