My H/C car in the sig has an issue stalling after startup (hot or cold). Once the car is running for about 1 min, it will not stall. Stalls usually after I start it and when trying to pull out of parking spot.

My tuner has not been able to figure it out yet. I have a Holly 90mm TB on the car and some guys in my area are state they have heard the Holley TB has a small IAC passage, and it might need to be bored out to correct this.... I did a search and came up with no information on this.....? Anybody elese heard of this?

Thanks
