Ran into an interesting issue. After my car was Dyno-Tuned, I had some major issues to fix, like replacing the intake, Injectors Sizing, and some of the wiring had to be replaced.. Everything was done over time, I am running a 406 sbc twin turbo and when the car starts up it runs great for the first 4 minutes or so. Then as I watch the IAC it will drop right to 0 and the car stalls. I will attempt start the car and it will start and run for a couple of seconds then immediately stall again. I noticed the IAC drops right to 0.. Any suggestion would be more than helpful at this point. Thank you.
