IAC Adjustment
#1 · April 21, 2019, 4:59 pm
I finally got my go EFI 30001 600hp system to start. I am having trouble getting my IAC under 50 after warm up. I have a sbc 350 with a mild cam. Slick fit headers with electric dumps and right side o2 sensor collector. There is no exhaust on it yet. It is not throwing codes and idle is actually good. I have it set for 800 rpm when warm and it will fluctuate a little between 780 to 900. I assume that may have to do with the lack of exhaust. Any tips would be greatly appreciated.

Must have exhaust installed. You are getting faulty O2 data when running open exhaust.
