Alright setting idle again removed the sprout and d/c iac. Start up the car idling rough with the screw in all the way. Turned the screw counterclockwise till i get the needle above the 500 mark more or less hovering there 500-700.

Alright turned off car, put in the spout and the iac try to crank it just cranks pump the gas car turns on but as soon as I let off dies. IAC right? ok so I remove the spout again and the iac just on a hunch try and crank again nope just crank. So i turn the screw all the way up again and crank starts then lower it again to the idle that im looking for not so rough. But same thing as before... what am I missing?? I am unable to test the IAC other then replacing it I do not have a multimeter.

Failed IAC - (no airflow to start engine). Press the throttle ¼ way down and try to start the car. If it starts, the IAC isn't working.

Once the base idle is est at 600+/-25 RPM, re-connect the IAC. The idle speed shoud increase from the 600 RPM mark to 650-725 RPM. If it does not the IAC isn't working.
